Answer:
120
Step-by-step explanation:
all complementary angles should add up to 180 degrees
3-----4
3-----4
3-----4
Total (Left): 9
Total (Right): 12
-------------------
Total (Left) + Total (Right) = 9 + 12 = 21
Answer:
50 deg
Step-by-step explanation:
The circles are congruent, so all radii of both circles are congruent.
The given central angles are congruent, so the triangles are congruent by SAS.
Since each triangle has 2 congruent sides (the radii), opposite angles are congruent.
m<DFE = m<J = 80 deg
m<H = m<G = x
m<H + m<G + m<J = 180
x + x + 80 = 180
2x + 80 = 180
2x = 100
x = 50
m<H = 50
