Question

Who will give me answers I mark hos name as brainlist​

Answer 1

Answer:

40°, 60°, 80°

Brainliest? Please do mark.

Step-by-step explanation:

Let the common multiple be x

Therefore sides= 2x,3x, 4x

Since sum of all angles of a triangle = 180°

Therefore,

2x+ 3x+ 4x=180°

9x=180°

Therefore x = 180/9 = 20°

Therefore, angles= 2x =2×20= 40°

3x= 3×20=60°

4x= 4×20=80°

Answer 2

Answer:

Let, the angles be x.

Then, the angles are 2x, 3x and 4x

According to the question,

2x+3x+4x=180° (Sum of all angles of a triangle is 180°)

=2x+3x+4x=180°

=9x=180°

=x=180°/9

=x=20°

Therefore, the angles are:-

2x=2×20°=40°

3x=3×20°=60°

4x=4×20°=80°
