Question

in a ABC if angle a is equal to 3 angle b is equal to 6 anglesey calculate angle a and angle b and angle c​

Answer 1

Answer:

Let 3∠A=4∠B=6∠C=x

∠A=3x,∠B=4x,∠C=6x

∠A+∠B+∠C=180∘

3x+4x+6x=180∘

x=240∘

Therefore,

∠A=80∘,∠B=60∘∠C=40∘

Answer 2

Answer:

sum of all angles of a triangle= 180°

let angle c be x

now,

<a+<b+<c = 180°

6+3+x= 180°

9+x=180°

x=180-9

x= 171

so, <c = 171°
