Question

Q2. One of the angles of a triangle is 120° and the other two angles are equal.
Find the measure of each of the equal angles.
O 30°, 30°
40°, 40°
O 45°, 45°​

Answer 1

Answer:

one angle = 120

let second angle = x

other angles equal so, angle second = angle third = x

sum of all angles of triangle = 180 degree

120+x + x = 180

120 + 2x = 180

2x = 180 - 120

2x = 60

x = 60/2

= 30
