Problema Solution
Find the angles of a triangle if one angle exceeds a second angle by 45 degrees and is three times as large as the third angle.
Answer provided by our tutors
Let first angle be x.
Given that second angle is 45 less than first. So it will be x-45
First one is three times as large as third
So third angle will be x/3
Sum of all angles of a triangle is 180
x+x-45+x/3 =180
2x+x/3=225
7x=675
x =96.42
First angle is 96.42
Second angle is 96.42-45=51.43
Third angle is 96.42/3=32.14
