Question

What is the value of x?
142
132
71
66

Answer 1

x = 66. It's an isosceles triangle so the bottom angles are both X. Triangles all equal 180 so you do 2x + 48 = 180. Subtract 48 from both sides to get 2x = 132. Divide by 132 by 2 to get 66. 

Answer 2

The value of x is 66 .

Explanation:

As given the figure in the question .

Sides of the two triangles are equal .

By using the property if two sides are equal there opposite angles are also equal .

Now by apply angle sum property of a triangle .

48 + x + x = 180°

2x = 180 - 48

2x = 132

`X= (132)/(2)`

x = 66

Therefore the value of x is 66 .
