Do the indicated mult. first:
7v - 2v + 16 = 5v + 20
5v + = 5v +20. This is never true. NO solution.

I used a calculator lol
Answer:
see explanation
Step-by-step explanation:
Given
tan a = =
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = = 41 , thus
sin a = =
cos a = =
The scale factor would be -8 because...
126 inches / 7 inches = 8 inches.
Because the car is bigger than the scale, it would be a negative scale factor.
