Question

Find out the value of m and the 3 angles, if the angles in the triangle are m - 40, m - 20, m + 60

Answer 1

Answer:

angles of triangle = m-40, m-20, m+60

sum of all angels of triangle = 180°

m-40 + m-20 + m+60 = 180°

3m = 180°

m = 60°

now, angles are

m-40 = 60 - 40 = 20°

m-20 = 60 - 20 = 40°

m+60 = 60 + 60 = 120°

angles of the triangle are 20°, 40° and 120° .
