Question 1194828
The second angle of a triangle is four times the first angle. The third angle of the triangle is 18 degrees less than the first angle. Find each angle of the triangle.
------------------
S, F & T = second, first and third angles
--------
S = 4F
T = F - 18
S + F + T = 180
----
4F + F + (F-18) = 180
6F - 18 = 180
F = 33 degrees
