Step-by-step explanation:

The trigonometric value identity is solved (cos x/1 + sin x) = sec x - tan x

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

Step-by-step explanation:

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...

⇒ hypotenuse = 84 (nearest whole number)

Answer:

84

Step-by-step explanation:

[tex] \sqrt{ {(40)}^{2} + {74}^{2} } = 84.1[/tex]

Answer:

magnitude of PÔS = 60°

magnitude of SÔQ = 120°

note: a straight line has always 180°

solve for x:

m∠POS

m∠SOQ

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.

Answer:

{ 14, 30, 33 }

Step-by-step explanation:

for the three sides to form a triangle.

The sum of any 2 sides > third side

{ 7, 22, 29 }

7 + 22 = 29 ← not greater than 3rd side, thus not form a triangle

{5, 7, 12 }

5 + 7 = 12 ← not greater than 3rd side, thus not a triangle

{ 8, 14, 24 }

8 + 14 = 22 < 24 ← sides do not form a triangle

{ 14, 20, 33 }

14 + 20 = 34 > 33

14 + 33 = 47 > 20

20 + 33 = 53 > 14

Thus the sides form a triangle

For the two parallelogram to be congruent, their corresponding sides must be equal

Two figures are said to be congruent if they are of the same shape and their corresponding sides and angles are congruent to each other. The SSS congruency theorem states that two figures are congruent of all their sides are congruent.

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.
