Question

The angles of triangle are in the ratio 2:3:4 fin the largest angle

Answer 1

Let the length of the angles- 2x, 3x and 4x

2x+3x+4x=180°  (reason- angle sum property of a triangle)

9x=180°

x= (180/9)°

x= 20°

Then,

the first angle= 2x= 2*20°=40°

the second angle= 3x= 3*20°=60°

the third angle= 4x= 4*20°=80°

confirmation- (40+60+80)°=180°

I hope this helps!

Answer 2

Hi there

2:3:4 = 180

2x+3x+4x=180

7x= 180

X=180÷7

X=20

Largest angle is 4x=4×20

There fore answer is 60
