Question

29. Find the values of the x and y in the following diagrams:
one of the angle is 50 degree
and the exterior angle is 120 degree
find the other two angels​

Answer 1

Answer:

120-50= 70 and other one 35

Answer 2

Given: One of the angles is 50 degree, the exterior angle is 120 degrees.

To Find: The values of the x and y

Solution:

The sum of two opposite interior angles is equal to its exterior angle.

        Let that interior angle be x

        x + 50 = 120

        x=120 -50

        x=70

Also, sum of the interior angle of a triangle is 180 degree

Therefore,

        50 + 70 + y = 180

                120 + y = 180

                          y = 60

Answer =Angles of the triangle = 50, 70 , 60
