Question

determine the value of x.....please solve it ​

Answer 1

Q.6 (a)

three angles of a triangle are 4x,5x+6,9x-6.

thus, by angle sum property,

4x+5x+6+9x-6=180

18x=180

x=10. thus, angles are 40,56,84.

(b).three angles of a triangle are 2x, 3x,5x.

thus, by a.s.p,

2x+3x+5x=180

10x=180

x=18. thus, angels are 36,54,90.

(c)three angles of a triangle are in ratio 3:4:5. let the required ratio be x

so, 3x+4x+5x=180

12x=180

x=15. thus, angles are 45,60,75.

hope it helps!!!!
