Problema Solution
Two angles are supplementary. One angle is 5 degrees less than four times the other. Find the measures of the angles
Answer provided by our tutors
let 'x' and 'y' be the angles
since x and y are supplementary we have
x + y = 180
one angle is 5 degrees less than four 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
