A triangle

A triangle has one angle of 63.1°, and the other two are in the ratio of 2:5. What are the measurements of the two angles?

Correct answer:

A =  63.1 °
B =  33.4 °
C =  83.5 °

Step-by-step explanation:

A=63.1=63.1=63°6
B:C=2:5  A+B+C=180 B=52 C 63.1+B+C=180 B=52 C  63.1+B+C=180 B=2/5 C  B+C=116.9 5B2C=0  Pivot:Row1Row2 5B2C=0 B+C=116.9  Row251 Row1Row2 5B2C=0 1.4C=116.9  C=1.4116.9=83.5 B=50+2C=50+2 83.5=33.4  B=5167=33.4 C=2167=83.5
