Question

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents. ​

Answer 1

9514 1404 393

Answer:

1. 85°
2. 60°

Explanation:

1. Angle JKL is half the measure of the intercepted arc JK.

(1/2)JK = 1/2(360° -190°) = (1/2)(170°) = 85°

angle JKL is 85°

__

2. The angle between tangents is the supplement of the intercepted arc.

angle JKL = 180° -(360° -240°)

angle JKL = 60°
