Problema Solution
two angles are supplementary, one angle is 5 degrees less than 4 times the other. find the measure of the angles
Answer provided by our tutors
let 'x' and 'y' represent the angles
Two angles are supplementary if they add up to 180 degrees thus:
x + y = 180
one angle is 5 degrees less than 4 times the other:
x = 4y - 5
by solving the system of equations:
x + y = 180
x = 4y - 5
we find:
x = 143 degrees
y = 37 degrees
