Question

What are m∠1 and m∠2?

Answer 1

B is the correct answer

Answer 2

Angle 1 = 35

Angle 2 = 30

Answer B

Explanation:

Angle 1)

You know the total angles in a triangle are 180

You also know that the angle across from 1, next to 115 has to be 180-115 (65) or , this gives you

180-80-(180-115)= 35

Angle 2 )

You know the total angles in a triangle are 180

You also know that the angle across from 85, next to 115 is the same value 65 as it was for the calculation of angle 1.

so this means

180-85-65 = 30
