Question

If m∠2= 137 and m∠P= 22, what is m∠O? answers are 43,21,65,115

Answer 1

21

Explanation:

since it is a triangle subtract 180 by 137 and 22

180-(137+22) or 180-132-22

hope this helps

Answer 2

21

Explanation:

We khow that the sum of a triangle's angles sizes is 180°

• 137+22 = 159°

substract the sum of the two khown angles from 180°

• 180°-159° = 21 °

so m<0 = 21°
