Answer:
P=143
Step-by-step explanation:
So, we know that P and Q are supplementary angles. In other words:
We also know that P is 5 less than 4 times Q. Thus:
Substitute the second equation into the first:
Find Q. Combine like terms:
Add 5 to both sides:
Divide both sides by 5:
So, Q is 37 degrees.
Q and P are supplementary, which means that P is 180-37 or 143 degrees.
And we're done!
