Answer 1

The solution to the trigonometric expression is given by [tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2}) =-\sqrt{\frac{3}{2} }[/tex]

What is an equation?

An equation is an expression used to show the relationship between two or more variables and numbers. Trigonometric functions are specific functions of angles. Examples are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

Given the equation:

[tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2} )\\\\tan(-\frac{2\pi}{3})=\sqrt{3} \\\\tan(\frac{7\pi}{4})=-\sqrt{2} \\\\tan(-\frac{\pi}{2})=0\\\\\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2} )=\frac{\sqrt{3} }{-\sqrt{2} }=-\sqrt{\frac{3}{2} }[/tex]

The solution to the equation is [tex]\frac{tan(-\frac{2\pi}{3}) }{sin(\frac{7\pi}{4}) } -sec(-\frac{\pi}{2}) =-\sqrt{\frac{3}{2} }[/tex]

3. What is the measure of side LM?

Answers

Answer:

LM = 8.75

Step-by-step explanation:

They’re asking us to find the hypotenuse (LM)

Given the angle measure of M which is 24° and it is adjacent to MK which is 8

so cos 24° = adj/hyp (adjacent / hypotenuse)

cos 24° = 8/hyp

hyp = 8 divided by cos 24°

hyp = 8.75

LM = 8.75

For every 2 pages of a book that Bernice reads, Charmaine reads 3. When Charmaine
had 16 pages left, Bernice had 36. How many pages are there in the book?

Answers

Answer:

76

Step-by-step explanation:

Let x = number of pages

Since Charmaine had 16 pages left, subtract 16 from x to indicate that is the number of pages read like this: x - 16

Divide that by 3 like this: (x - 16)/3

Do the same for Bernice: (x - 36)/2

Make them equal to each other

(x - 16)/3 = (x - 36)/2

Cross multiply

2(x - 16) = 3(x - 36)

Distribute

2x - 32 = 3x - 108

Move like terms to the same side by subtracting 2x from both sides

2x - 32 = 3x - 108

- 2x         - 2x

-32 = x - 108

Add 108 to both sides

-32 = x - 108

+ 108    + 108

x = 76

This means there are 76 pages in the book.

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

To verify the identity (cos x / (1 + sin x)) = sec x - tan x, we need to simplify the right-hand side of the equation using trigonometric identities and see if it matches the left-hand side.

sec x - tan x = 1/cos x - sin x/cos x = (1 - sin x)/cos x

On simplifying , we get

cos x / (1 + sin x) = cos x / (1 + sin x) * (1 - sin x)/(1 - sin x) = cos x * (1 - sin x) / (1 - sin²x)

Using the Pythagorean identity sin²x + cos² x = 1, we can substitute 1 - cos²x for sin²x in the denominator:

So , cos x / (1 + sin x) = cos x ( 1 + sin x ) / cos²x

On further simplification , we get

cos x / (1 + sin x) = cos x / cos²x + cos x ( sin x ) / cos²x

cos x / (1 + sin x) = ( 1/cos x ) + ( sin x / cos x )

From the trigonometric relations , we get

cos x / (1 + sin x) = sec x - tan x

Hence , the trigonometric equation is solved

What is the length of the hypotenuse of the triangle when x=10​?

The length of the hypotenuse is about

Answers

Answer:

84 (nearest whole number)

Step-by-step explanation:

If x = 10,

Longest leg = (7 x 10) + 4 = 74

Shortest leg = 4 x 10 = 40

Using Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse of a right triangle):

⇒ 74² + 40² = c²

⇒ 7076 = c²

⇒ c = √7076 = 84.11896...

Sarah's brother is 12 less than twice her age. If Sarah is 16, what equation represents this situation?

Answers

The equation that can be used to represent the ages of Sarah and his brother will be 2x - 12 = 16.

How to solve the equation

From the question given, Sarah's brother is 12 less than twice her age and Sarah is 16.

Let Sarah's age be represented by x.

Therefore, the equation to represent the situation will be:

= (2 × x) - 12 = 16

2x - 12 = 16

2x = 16 + 12.

2x = 28

x = 28/2 = 14

PQ is a straight line segment.According to the information marked in the figure, (I) Find the magnitude of PÔS. (ii) Find magnitude of SÔQ.



PLEASEEEEEEE HEELPPP!!
99 POINTS!! btw turn the attached picture upside down​

Answers

Answer:

magnitude of PÔS = 60°

magnitude of SÔQ = 120°

note: a straight line has always 180°

solve for x:

PÔS + SÔQ = 180°3x + 2x + 80° = 180°5x = 180° - 80°5x = 100°x  = 20°

m∠POS

3x 3(20°)60°

m∠SOQ

2x + 80°2(20°) + 80°40° + 80°120°

So to find angle POS and SOQ we have to find value of x first.

[tex] \\ [/tex]

[tex] \rm \angle POS + \angle SOR + \angle ROQ = 180 \degree \\ [/tex]

Reason:-

Sum of angles on same line.

By the way it can be any number of angles but they should meet at same point. And their sum is always 180°. Remember linear pair? It is also same aspect but there will be only two angles.

[tex] \dashrightarrow \sf \angle POS + \angle SOR + \angle ROQ = 180 \degree \\ [/tex]

[tex] \dashrightarrow \sf 3x + 2x+ 80= 180 \degree \\ [/tex]

[tex] \dashrightarrow \sf 5x+ 80= 180 \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf 5x= 180 - 80 \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf 5x= 100 \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf x= \dfrac{100}{5} \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf x= \dfrac{5 \times 20}{5} \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf x= \dfrac{\cancel5 \times 20}{\cancel5} \degree \\ [/tex]

[tex] \\ [/tex]

[tex] \dashrightarrow \sf x= \dfrac{1 \times 20}{1} \degree \\ [/tex]

Verification:-
