Answer:
d=8$
Step-by-step explanation:
we know that the shaded side is 90 degrees and we are given 28 degrees
So we add 90+28 and we get 118
Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure
180-118=62
x=62
Your equation is 180=90+28+x
3x^2 / 4 = 48
Multiply both sides by 4 to get rid of the four on the left.
3x^2 = 192
Divide both sides by 3
x^2 = 64
The square root 64 to get x
Remember there are two answers
x = 8 and x = -8
