Question

Find the value of x and y

Answer 1

Answer:

x = 70° and y = 40°

Step-by-step explanation:

140° + x = 180° [Linear Pair]

x = 40°

Let the third angle inside the triangle be z

Now, x = z [ Angles opposite to equal sides are equal]

x + z = 140 [Exterior Angle Property]

2x = 140

x = 70
