Answer:

The measurement of Angle ABC is 30°

Explanation:

1) Identify the problem

The problem is an Angle Formed Outside of Circle By Intersection

Which is ( Two Tangents)

2) Formula For Angle Formed by Two Tangents

m<ABC= 1/2 (mADC-mAC)

ADC is the major arc and AC is the minor arc.

3) solve For angle B or m<ABC

m<ABC=1/2 (210-150)

m<ABC= 60 ÷ 2

m<ABC= 30°

Hopes This helps!

Have a great Day :D

Answer:

I believe it would be 75 degrees, you may want to double check but based on the postulate on arc addition, I think this is correct.
