<h3>Answer:   77/85</h3>

Explanation:

Triangles HIG and FED are similar triangles. We know this because we have two pairs of angles that are congruent (angle G = angle D; angle I = angle E). Use the AA (angle angle) similarity theorem.

Since angles G and D are congruent, computing sin(D) is equivalent to finding sin(G)

sin(angle) = opposite/hypotenuse

sin(G) = IH/HG

sin(G) = 77/85

sin(D) = 77/85

Average= 9.625
average is when you add up all the numbers and divide by how many there are..
x,21,27,21,16,-2,-9,9
(x+21+27+21+16+-2+-9+9)/8=9.625
×8 both sides
x+21+27+21+16+-2+-9+9=77
x+83=77
-83 both sides
x= -6 degrees
