3x+5x-12=180
8x=180+12
8x=192
x=192/8
x=24
angle 1 = 5x-12
=5(24)-12
=120-12
=108
angle 2= 3x =3*24=72
angle 1 = angle 9
angle 9= 108
Answer:
Step-by-step explanation:
A rectangle had a length of 2x-7 and a width of 3x+8y
Perimeter P = 2(l + w)
P = 2(2x - 7 + 3x + 8y)
P = 2(5x + 8y - 7)
P= 10x + 16y - 14
