Label the 2 angles, one is x and the other is 8x.
90 = 8x + x
90 = 9x
10 =x
10 times 8 = 80. this is 8x.
10(which is x) + 80 (which is the 8x) = 90.
Answer: (4,8)
First you have to solve for Y in either equation. I solved for Y in the second equation and my new equation was y=12-x.
Then you plug this new equation into the equation you did not touch. It will become 3x+ (12-x)=20.
Next you solve this equation for X which would be 4.
Lastly you plug in 4 in either equation. I plugged it in the first equation and it became 3(4)+y=20
I hope this helps some :)
