How do i find x with this diagram

x=32

Step-by-step explanation:

that is an isosceles triangle, meaning 2 sides are the same and 2 anlges are the same.

each traingle = 180 degrees

3x+2(x+10)=180

3x+2x+20=180

5x=160

x=32

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
