E and F are complementary. If m E = 9x - 38 and mF = 2x + 40, find m F pls I need help

Step-by-step explanation:

If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°

To find mF add mE and m F and equate it to 90 to find x then substitute it into the expression for mF

Thats

mE + mF = 90

9x - 38 + 2x + 40 = 90

11x + 2 = 90

11x = 90 - 2

11x = 88

Divide both sides by 11

x = 8

Now we have

if m F = 9x - 38

m F = 9( 8) - 38

mF = 72 - 38

We have the final answer as

Hope this helps you

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
