Answer:
x = 12.75
y = 12
Step-by-step explanation:
To solve for x, we can see that it makes up a right angle when placed next to the 31 degrees.
We also know that the corner should equal 90 degrees, so we can set this up:
4x+8+31=90
Group like terms:
4x=51
Divide:
x=12.75
To solve for y, we can see that two expressions equal the same length, so:
8y+26=3y+86
Group like terms:
5y=60
y=12
You can also plug in x and y in to see if they match up
4(12.75)+8+31=90
51+8+31=90
90=90
and
8(12)+26=3(12)+86
96+26=36+86
122=122
