posted by .

the measures of the angles of (triangle) RST are in the ratio 2:3:5. find the measures of each, and classify the triangle as acute, right, obtuse.

• pre algebra -

2x+3x+5x = 180
10 x = 180
x = 18
2x = 36 , 3x = 54 etc

• geometry -

2x+3x+5x=180
10x/10=180/10
x=18
2x=2(18)=36
3x=3(18)=54
5x=5(18)=90
