The measures of the 3 angles of a triangle is in the ratio of 4:5:6. Find their measures

 

Sagot :

Pauviz
let x be the number
4x+5x+6x=180 (since the total measurement of angle in a triangle is 180)
15x=180
x=12(to get 12 divide 180 by 15 to isolate x)
the substitute x
if x=12
4(12)+5(12)+6(12)=180
48+60+72=180
180=180
