Question 939951
Two angles are complementary. One angle is 12degrees larger than the other . Using two variables x and y, find the size of each angle by solving a system of equations.
-------
Equations::
x + y = 90 degrees
x = y + 12
-------
Substitute for "x" and solve for "y"::
y+12 + y = 90
2y = 78
y = 39 degrees
----
x = 90-y = 90-39 = 51 degrees
------------
You are correct.
