Question

Whats perimeter of this triangle​

Answer 1

34

Explanation:

2x = 3x-5

x = 5

2x = 10

3x - 5 = 10

19 - X = 14

10 + 10 + 14 = 34

Answer 2

38

Explanation:

because the angles are congruent you 3x-5 and 19-x are equal to each other, so solve for x using these equations:

3x-5 = 19-x

+5 +5

3x = 24 - x

+x +x

4x = 24

/4 /4

x = 6

Insert x into each equation and add all the answer together to get the perimeter:

3(6)-5 = 13

19-6 = 13

2(6) = 12

13+13+12 = 38
