a) 40 degrees, 60 degrees, 80 degrees

b) 60 degrees, 80 degrees , 40 degrees

c) 80 degrees, 40 degrees, 60 degrees

d) 40 degrees, 50 degrees , 90 degrees.

​

Answer 1

Answer:

This might help you

Explanation:

2x+3x+4x=180

,9x = 180

x= 180/9=20

Ans: 2x20=40 degree, 3x20= 60 degrees and 4x20= 80 degrees

Answer 2

$\huge\sf\underline\red{Answer:-}$

option-A

Step by Step explanation:-

Concept used:-

In a triangle sum of three sides is 180°

Solution:-

Given ratio 2:3:4

So let the angles are 2x,3x,4x

We know that sum of angles in a triangle is 180°

2x+3x+4x=180°

9x=180°

x=20°

Therefore 2x=40°

3x=60°

4x=80°

Therefore Required angles are 40°,60°,80°

Verification:- So angles are 40°,60°,80°

Sum is 40°+60°+80°=180°

Hence verified! So answer is option a
