pre algebra

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
