Find the perimeter of ABC

32

P= 4+4+16=24 units

Step-by-step explanation:

The triangle is isosceles so <B is congruent to <C. So you can set the measures of these to angles equal to each other and solve for x.

x+6 = 2x -20

26 = 2x-x

26=x

so the measure of <B is 6+26=32

the measure of <C is 2 (26)-20 =32

m<B= 2(BC)

32 = 2(BC)

32   = BC

2

16=BC

m<C=8(AB)

32=8(AB)

32 =(AB)

 8

 4 =AB

Since the triangle is isosceles AC will also be four.

P= 4 +4+16

P=24 unit

answer: i guess 5 units?
