# A triangle

A triangle has an angle that is 63.1 other 2 are in ratio of 2:5 What are the measurements of the two angles?

Correct result:

A =  63.1
B =  33.4
C =  83.5

#### Solution:

A = 63.1
A+B+C = 180
B = 2/5 • C

A = 63.1
A+B+C = 180
5B-2C = 0

A = 631/10 = 63.1
B = 167/5 = 33.4
C = 167/2 = 83.5
