Find the measure of AB⎯⎯⎯⎯⎯⎯⎯.

A. 4
B. 7
C. 10
D. 5

By intersecting secant theorem:-

your answer is B) 7

---------------------------

hope it helps...

have a great day!!

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
