Answer 1

I'm guessing this is in a triangle and you need to find x?

Answer 2

ill draw a picture hold on

Answer 3

:)

Answer 4

Ah I see, well what you need to notice is that AOC=AOB+BOC. Can you see how this is?

Answer 5

yeah but i dont know how to solve it and eliminate all

Answer 6

Using what I just said, you can substitute the equations that you're given in the question:
4x-1+2x+15=8x+8
Do you see what I did? Can you rearrange this to find x?

Answer 7

got it! x = 3 thank you!!

Answer 8

Brilliant, well done :)

Answer 9

and last question:)

Answer 10

<ABC and <EBF are a pair of vertical angles; m<ABC = 3x + 8 and m<EBF = 2x + 48. What are m<ABC and m<EBF

Answer 11

If I told you that vertical angles are equal, could you set up an equation which you could solve?

Answer 12

3x + 8 = 2x + 48

Answer 13

Yes :)
