Question

who will give me the answer on paper I mark his name as brainliat​

Answer 1

let angles= 2x,3x,4x

thus,

2x+3x+4x=180(sum of the angles of a triangle)

9x=180

x=20°

Answer 2

Answer:

Let the angles be 2x, 3x and 4x

So 2x +3x+4x=180 degree

(angle sum property)

9x=180

x=180 divided by 9

x=20 degree

Therefore,

2x=2×20=40 degree

3x=3×20=60degree

4x=4×20=80 degree

So

40 degree, 60 degree and 80 degree are angles of triangle.
