Question

Identify m∠JKL, given that JK is a tangent line. HELP PLEASE!!

Answer 1

The measure of angle JKL is m∠JKL=35°

Explanation:

step 1

Find the measure of the arc KL

we know that

arc KL+arc KN+arc NL=360° ----> by complete circle

arc KL+150°+140°=360°

arc KL=360°-290°=70°

step 2

Find the measure of angle JKL

we know that

The inscribed angle is half that of the arc it comprises.

so

m∠JKL=(1/2)[arc KL]

substitute

m∠JKL=(1/2)[70°]=35°
