Question

Find the values of x and y in the following figures.​

Answer 1

Answer:

two sides are equal...so the angles opposite to the equal sides are equal.

therefore y=50

in the triangle ,exterior angle = sum of opposite interior angles

therefore x=50+50=100

Step-by-step explanation:

Answer 2

Answer:

y°=50°,x=100°

Step-by-step explanation: y°=50° because y° and 50° are opposite interior angles.Since,opposite interior angles are equal.

x°=100° Here we can follow exterior angle property which means the sum of the opposite interior angle is equal to the exterior angle.

Here 'exterior angle' means x°.(which is outside the triangle)

And here 'opposite interior angle' means the y° and 50° which means the angles opposite to the exterior angle and opposite to each other.
