Answer 1

Answer:

x = 81 and y = 18.

Step-by-step explanation:

From the figure,

Two sides of the given triangle are equal, so the given triangle is an isosceles triangle.

From the properties of isosceles triangle, we know : -

Angles containing equal sides remain equal.

So,

= >  x = 81°

And,

From the properties of triangle, we know : -

Sum of all angles of triangle = 180°

So,

= > y + 81 + 81 = 180

= > y = 180 - 162

= > y = 18

Therefore,

x = 81 and y = 18.
