Question

What is the value of m∠3, in degrees, if m∠5 = 70° and m∠2 = 60°?

Answer 1

50 degrees

Explanation:

Answer 2

m<3 = 50 degrees

Explanation:

All the angles of a triangle must add up to 180, or else it isn't a triangle

So, 70 + 60 + m<3 = 180

130 + m<3 = 180

m<3 = 180 - 130

m<3 = 50
