Question 405482: In a triangle, find the measures in degrees of all three angles if the measure of the second angle is four times the measure of the first, and the third angle is 45 degrees more than the second.

first angle =x
second angle = 4x
third angle = 4x+45
...
x+4x+4x+45=180
9x+45=180
add -45
9x=135
x=15 ===> first angle
4x=4*15=60===>second angle
4x+45= 4*15+45=105====>third angle
