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
