Answer:

13

Step-by-step explanation:

Write an equation setting the lengths equal to each other.

5x + 3 = 2x + 9

Move the variable (x) to one side. I'm going to subtract 2x from both sides.

5x - 2x + 3 = 2x - 2x + 9

3x + 3 = 9

Subtract 3 from both sides

3x +3 - 3 = 9 - 3

3x = 6

Divide both sides by 3

3x/3 = 6/3

x = 2

Now use 2x + 9 to find the length of EG by substituting 2 in for x.

2x + 9

2(2) + 9

4 + 9

13

You could also use 5x + 3 to find the length of EG by substituting 2 in for x.

HELP ME PLEASE ASAP!

Answer:

x=28

Step-by-step explanation:

Usually triangles equal 180 so if that's the case then you just add all of the angles together and set it equal to 180. So your equation should be 50+ 2x+ 3x-10= 180 and then solve that equation and you will end up with x=28. Hope this helped!!
