Circle F is congruent to circle J, and ZEFD = ZGJH.<br> m ZDFE = 80'. What is the measure of H?
djyliett [7]

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
