Answer 4

I can help

Answer 5

ok

Answer 6

So first you need to set up an equation. You already have the left side (5x + 15), now you just need what it is equal to. Can you tell me that?

Answer 7

Um i dont know lol.

Answer 8

How many degrees in a right angle?

Answer 9

90 degrees @hihi67

Answer 10

Exactly. So now we have 90=5x+15
Do you follow?

Answer 11

yes

Answer 12

Okay, do you know how to solve equations? Cause if you do then you should be able to continue on your own

Answer 13

yes i do but i dont know how to solve this one

Answer 14

So first you subtract 15 on each side: 90=5x-5 |-15
This results in: 75=5x
Then you simply divide by 5 on each side: 75=5x |/5
This results in: x = 15

Answer 15

I know you said you can solve equations, but I suggest you study that a bit more in detail, because the equation I just did was really, really basic.

Answer 16

ok thank you
