Answer:
X=14, Y=145
Step-by-step explanation:
We'll start by finding x. We know that angles that make a line are 180 degrees. Therefore we can say
5x-15+9x-1=180
add the similar numbers
14x-16=180
add 16
14x=196
divide by 14
x=14
Now to find y, we will solve for 9(14)-1= 125 and set that equal to y-20
y-20=125
add 20
y=145
