Question

Find the value of x and y ​

Answer 1

Answer:

x = 180-110=70 ( Linear pair)

The other angle of triangle is also 70 because of isosceles triangle

therefore y = 180-140=40 (Triangle angle sum )

Answer 2

180 - 110 = 70 (x)

Since 2 sides of the triangle are equal,

Then, 70² = 140

therefore, 180 -140 = 40(y).
