Answer:
x = 5
Step-by-step explanation:
Since it is an isosceles triangle then the two sides that have the same angle measurement have the same length. So:
5x - 8 = 2x + 7
---------------------------------------------------------------------
<h3>From here, its just basic equations:</h3>
5x - 8 = 2x + 7
Add 8 to both sides:
5x = 2x + 15
Subtract 2x from both sides:
3x = 15
Divide by 3:
x = 5
