Question 908347
if angle a and angle b are a linear pair and measure of angle a equals 4 measures of angle b, find measure of angle a and measure of angle b
------------------
Equations:
a + b = 180 degrees
a = 4b
----
Substitute for "a" and solve for "b"::
4b+b = 180
5b = 180
b = 36 degrees
Then a = 180-36 = 144 degrees
