Question

Find the value of x.

Answer 1

Value of
`x=-12`

Explanation:

The given triangle is isosceles

Here

`m\angle2+m\angle2+36^0=180^0\\\\2m\angle2=144^0\\\\m\angle2=72^0\\\\x+84=72\\\\x=72-84\\\\=-12`

Answer 2

`m∠2+m∠2+36⁰= 180°`

`2m∠2 = 144°`

`m∠2 = 72⁰`

`x +84 = 72`

`x = 72 - 84`

`x= -12`
