Question

if angles A,Band C in a triangle ABC are 3x,5x and 8x +4 respectively ,then find all the three angles​

Answer 1

Step-by-step explanation:

let A,B,C be 3 x 5 x and ( 8x+4)

A + B + C equal to 180°

therefore,

3 x + 5 x + 8 x+4 = 180 degree

8x+8x+4=180°

16x=180°-4

x=176/16

x=11

A=3x =3*11=33°

B=5x =5*11=55°

C=8x+4 =8*11+4=88+4=92°
