Question

In right triangle AABC,
MLA = 73º. Find m2B.
What is the degrees

Answer 1

17degrees

Explanation:

Since the triangle ABC is a right angled triangle, one of the angle is 90 degrees

The sum of angle in a triangle is 180

m<A + m<B + m<C = 180

73 + 90 +m<C = 180

163 +m<C = 180

m<C = 180-163

m<C = 17 degrees

Hence the third angle is 17degrees
