Question

What is the value of x in this triangle

Answer 1

`\angle x=46^o`

Explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

so

The triangle of the figure is an isosceles triangle because has two equal sides

therefore

Remember that the sum of the interior angles in a triangle must be equal to 180 degrees

so

`2\angle x+88^o=180^o`

Solve for angle x

`2\angle x=180^o-88^o`

`2\angle x=92^o`

`\angle x=46^o`
