Can someone pls help me i don’t ll get this

Answer 1

Answer: 6

Explanation:

Angles opposite congruent sides in a triangle are congruent, so both angles are equal to
`(13x-6)^(\circ)`.

Since angles in a triangle add to
`180^(\circ)`, so:

`36+2(13x-6)=180\\\\2(13x-6)=144\\\\13x-6=72\\\\13x=78\\\\x=6`
