Answer:
x = 3 and x = -3
Step-by-step explanation:
/x/ - 8 = -5
Add 8 to both sides
/x/ -8 + 8 = -5 +8
/x/ = 3
/ x / will be always positive as it is absolute value of x. So, x = 3 & x= -3
Answer:
a.|-5| or 5
b.|12.9| or 12.9

We will be using the cosine function to figure this out.
The ramp, ground, and platform form a right triangle.
The hypotenuse is 29, and the side adjacent to ∠x is 20.
SO:
Cos ∠x = 20/29
Cos ∠x = 0.68965517241379
Use the function on your calculator to find what angle has a Cos of 0.6896551
Cos 0.6896551 = 46.397°
ANSWER: the angle of elevation is 46.4°
