Answer:

Step-by-step explanation:

The parallel lines divide the transversals proportionally.

The green length = 24 - c , then

$\frac{24-c}{20}$ = $\frac{c}{12}$ ( cross- multiply )

12(24 - c) = 20c ← distribute left side

288 - 12c = 20c ( add 12c to both sides )

288 = 32c ( divide both sides by 32 )

9 = c

Then

green length = 24 - 9 = 15

FG=1.9 because since they are congruent Sr=FG

S=75° because they are congruent so G=75° so S=75°
