Question

What is the measure of the exterior angle x in the given figure? Write the proof.​

Answer 1

Answer:

-[y-x²-{5x²+y-(8x²-y-3x

Step-by-step explanation:

x in the given figure? Write the proof.

Answer 2

Step-by-step explanation:

The sum of interior angles = 180

Therefore, the third interior angle = 180-(50+90)

= 40

Now the exterior angle of a triangle =

the sum of opposite interior angles which is 50+90=140

:. x = 140
