Problema Solution
Angle TRS is a straight angle. Angle TRX is a right angle. If angle TRS = 2x+5y, and angle XRS = 3x+3y, solve for x and y.
Answer provided by our tutors
Since the straight angle equals 180 we have:
2x + 5y = 180
The right angle equals 90 degrees:
3x + 3y = 90
We have the following system of equations:
2x + 5y = 180
3x + 3y = 90
