So the side length became 0.6*5 = 3 cm.
<span>-34-r=-7(8r-3)
- 34 - r = - 56r + 21
- r + 56r = 21 + 34
55r = 55
r = 55/55
r = 1</span>
To find the indicated angle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the adjacent side and the hypotenuse. Therefore, we should use cosine to solve.
cos(x) = 12/36
x = cos^-1(12/36)
x = 71 degrees
Hope this helps!
Answer:
Suzy got the best deal per once
Step-by-step explanation:
Answer: Choice D) 
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on 
to make it a one-to-one function, to make the inverse a function. One possible domain restriction is 
which would lead to the inverse function
