Question

HELP NEEDED Help me figure this out

Answer 1

Answer: 252

Explanation:

First we need to find y.
Because there are three marks indicating that the measure of the angles are congruent, we know that all sides of the triangle are equal, so we can use that to find y.

5y-6=4y+12
y=18

Now substitute y into all the side equations:
5y-6 = 5(18)-6 = 84
4y+12 = 4(18)+12 = 84
6y-24 = 6(18)-24 = 84

Now that we know all the sides, just add these values together to get your perimeter:
84+84+84= 252

Answer 2

Answer:

y=18 P=252

Step-by-step explanation:

By plugging in 18 to each you get 84 for each side of the triangle. And by adding them all together the perimeter is 252.
