Answer:
I can't really see because it's blurry but if you're solving for x then...
x=13
Explanation:
77+90+x=180
167+x=180
-167 -167
x = 13 The points you gave are enough.
FGD and 77 are complementary Added together they equal 90 degrees.
<FGD = 90 - 77
<FGD = 13
<FGD and x are vertically opposite angles.
Vertically opposite angles are equal.
x = 13
