Find the measure of the indicated angle.Answers:A: 211B: 81C: 119D: 89

Answer 1

Answer:

89°

Step-by-step explanation:

Ok so the measure of a triangle is 180°.

We have one angle, so we need to find m∠ACB.

A line is 180°.

180-150= 30.

m∠ACB=30°.

m∠BAC=61°.

180-(61+30)=89°

Answer 2

Answer:

D. 89

Step-by-step explanation:

all interior angles of a triangle have to equal 180°.

180-150=30

30+61=91

180-91=89°
