Question

If m<18 = 46° and m<13 = 69°, calculate m<10.

Answer 1

m<10 = 65°

Explanation:

I. Given m<18 = 46deg, m<13 = 69deg and m<10 = x

The degree is less than 90deg, so this triangle is acute triangle.

Sum of degree inside of triangle is 180°

So 46 + 69

= 115

Find x by

180 - 115 = 65

So m<10 = 65°

Hope that help :)
