HI,
*Note: the sum of supplementary angles is 180 degrees
Let x larger angle
would be the other
.
.
simplify and solve for x
.
Multiply each term on both sides of the equation by 5
5x + 4x - 135 = 900
9x = 1035
x = 115 degrees ( IS THE LARGER ANGLE)
.
check Your answer:
(4/5)*x - 27) = 65degrees (then the smaller one)
115degrees + 65degrees = 180degrees
