Answer:
x =12
Step-by-step explanation:
Since this is an isosceles triangle the angles at the bases of the equal sides are equal
The unmarked angle is 4x
The 3 angles of a triangle total 180 degrees
4x+4x+ 84 =180
Combine like terms
8x +84 = 180
Subtract 84 from each side
8x +84-84 = 180 -84
8x =96
Divide by 8
8x/8 = 96/8
x =12
