Question

In triangle ABC, the measure of angle ABC is 51°

and ACB is a right angle. What is the measure of
angle BAC in degrees?

Answer 1

39 degrees

Explanation:

The sum of angle in the triangle ABC is a80 degrees

m<ACB + <BAC + <ABC =1 80

90 + <BAC + 51 = 180

141 + m<BAC = 180

m<BAC = 180-141

m<BAC = 39 degrees

Hence the measure of m<BAC is 39 degrees
