Answer:
x = 30
F = 130
G = 50
Step-by-step explanation:
f and g are supplementary which means they add to 180
5x-20 + 3x - 40 = 180
Combine like terms
8x - 60 = 180
Add 60 to each side
8x-60+60 = 180+60
8x = 240
Divide by 8
8x/8 = 240/8
x = 30
F = 5x -20 = 5*30 -20 = 150 -20 = 130
G = 3x-40 = 3*30 -40 = 90-40 = 50
the answers that you've provided are, in fact, correct.

Answer:
Angle A = 18°
Step-by-step explanation:
since the angles are complementary, they add up to 90°
(2x-4) + (5x+17) = 90
add like terms
7x-4+17=90
simplify left side
7x+13=90
subtract 13 from both sides
7x=77
divide both sides by 7
x=11
plug in x to find the measure of angle A
2(11) - 4
multiply 2*11 first
22-4
simplify
18
