Answer:

x=15.5

Step-by-step explanation:

since ABC is isosceles two sides should be equal

A=48

B=4x+4 , since 2 sides should be equal B and C are equal

therefore C is also equal to 4x+4

ADD ALL:

48+4x+4+4x+4=180

48+8x+8=180

8x+56=180

Transpose 56 so its gonna be (-56)

8x=180-56

8x=124

DIVIDE BY 8:

x=15.5
