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
-5+d/3=5
d/3-5=5
d-3.5/3=5
d-15/3=5
d-15=15
(d-15)+15=15+15
d-15+15=30
d=30
