Answer:
the value is x is 8 and y is 7
Sum of exterior angle of a polygon is 360
90 + 10x + 5x + 45 = 360
135 + 15x = 360
15x = 360 - 135 = 225
x = 225/15 = 15
Largest exterior angles = 10x = 10(15) = 150 degrees.
Hi!
<u>Given these two equations:</u>


We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

Combine like terms on both sides:

Subtract y from both sides:

Subtract 8 from both sides:

Now, we can simply plug the y value in to the first equation, and solve for x:

Simplify:

<h3>
Therefore, x is equal to 12 and y is equal to 4.</h3>
