Question

29. If two angles of a triangle are equal and the third one is greater
than each of them by 30°, what is the measure of the third
angle?​

Answer 1

Answer:

Step-by-step explanation:

Let the two angles that are equal be x

Now, x + x +( 30 + x ) = 180 degree

3x + 30. = 180 degree

3x. = 180 - 30 degree

3x. = 150 degree

x. =. 150 / 3 = 50 degree

Angle 1 = 50 degree

Angle 2 = 50 degree

Angle 3 = x+ 30 = 50 + 30 = 180 degree
