Question

13. In the given figures, find x, y or z (whichever is required)
​

Answer 1

Answer:

acute angle or obtuse angle

Answer 2

Answer:

x = 50°

Step-by-step explanation:

x = x ( angles opposite to equal sides are equal in length )

x + x + 80° = 180° ( angle sum property of a triangle )

2x + 80° = 180°

2x = 180 - 80 = 100°

x = 100 / 2 = 50°
