Work out the size of angle x.
Answer:
120°
Step-by-step explanation:
since 60° and x are alternate interior
you get this equation
60° + x = 180
subtract 60 from both sides
x = 120

Trigonometry. Find the value of x. Round to the nearest tenth. I been stuck on it for a while I need help.
Answer:
x= 256.8(rounded)
Step-by-step explanation:
For this problem, use tangent because you have adjacent and are trying to find the opposite side from the angle. Tan(15°)= x/300 so x=300tan(15°)
It was negative, but you probably take absolute value.
Help me plz I need lots of help
Answer:
18x + 16
Step-by-step explanation:
(Not simplest form) 9x + 9x + 8 + 8
To get simplest form, just add the terms and integers together, which in this case would give you 18x + 16.

Solve the following system of equations.
4x + 2y = 8
4x + 3y = 16
Answer:
x= - 2, y=8
Step-by-step explanation:
4x+2y=8 ... (1)
4x+3y=16 ... (2)
(1)-(2): -y= - 8
y=8
Substitute y=8 into any equation
Exp: 4x+2(8)=8
4x+16=8
4x= - 8
x= - 2
If the terminal point determined by t is (-5,-4), then
\sin (t) =
;
\cos (t) =
;
\tan (t) =
.
Answer:
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].
Step-by-step explanation:
Let [tex]\vec u = (x,y)[/tex]. From Trigonometry, we remember the following definitions for the trigonometric ratios, dimensionless:
[tex]\sin t = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)
[tex]\cos t = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)
[tex]\tan t = \frac{y}{x}[/tex] (3)
If we know that [tex]x = -5[/tex] and [tex]y = -4[/tex], then the trigonometric ratios are, respectively:
[tex]\sin t = \frac{-4}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\sin t \approx -0.625[/tex]
[tex]\cos t = \frac{-5}{\sqrt{(-5)^{2}+(-4)^{2}}}[/tex]
[tex]\cos t \approx -0.781[/tex]
[tex]\tan t = \frac{-4}{-5}[/tex]
[tex]\tan t = 0.8[/tex]
The trigonometric ratios associated with (-5, -4) are [tex]\sin t \approx -0.625[/tex], [tex]\cos t \approx -0.781[/tex] and [tex]\tan t = 0.8[/tex].

What is 43 percent of 84
Answer:
36.12
Step-by-step explanation:
43% of 84 can be rewritten to 43% * 84 or 43/100 * 84.
43/100 * 84/1 = 3612/100
3612/100 = 36.12
Answer:3612 you have to mulpliy 43 by 84 and will get 3612

An angle bisector sets up a triangle ratio that looks like the following proportion.
3x - 3 5x
====== = ====== Cross multiply
24 44
44*(3x-3) = 24*5x Remove the brackets on the left
132x - 132 = 24*5x Combine the right side
132x - 132 = 120x Add 132 to both sides
132x = 120x + 132 Subtract 120x from both sides
132x- 120x = 132 Combine
12x = 132 Divide by 12
x = 11

Marta walked at 4.9 mile per hour for 0.89 miles. How fa did she walk?
Answer:
2.808 hope this helps :)
Answer:
I think it would be .89 miles because it says that she walked that distance.
Step-by-step explanation:
If it gives you the distance she walked, the speed won't change the distance traveled, only the amount of time paired with speed would change the distance.

O 90°
ОООО
120°
210°
Answer:
∠b + ∠c + ∠e = 120°
Step-by-step explanation:
From the attached figure,
∠b + ∠e + ∠a = 180° (Linear pair)
Given that, ∠a = 90°
∠b + ∠e = 90° ...(1)
Also,
∠c + ∠d = 180° (Linear pair)
Given that,
∠d = 150°
∠c = 180°-150°
= 30°
Adding ∠c to both sides of the equation (1).
∠b + ∠e + ∠c= 90° + ∠c
∠b + ∠c + ∠e = 90° + 30°
= 120°
Hence, the meaure of ∠b + ∠c + ∠e is equal to 120°
