Question

Answers :
A. 80 degrees
B. 180 degrees
C. 110 degrees
D. 140 degrees

Answer 1

D) 140 degrees

Explanation:

Radius is perpendicular to tangent line

Draw DA, construction

DA is an angle bisector, m<BAD = 20,

Now, DBA and DCA are congruent right triangles

This is due to LA congruency

90 + 20 + x = 180

x = 70

BDA = CDA

so 70 + 70 = 140

D) 140 degrees
