Question

Given: DR is the tangent to Circle O. If m of angle RDC = 150, then m DAC = A. 75 B.150 C.300

Answer 1

300

Explanation:

Answer 2

C. 300

Explanation:

We are told in the question that:

DR is the tangent to Circle O. If m of angle RDC = 150, then m DAC

Using the Tangent Chord Theorem

<RDC = DAC/ 2

150 = DAC/2

Cross multiply

DAC = 150 × 2

DAC = 300
