Question

The ratio of the measure of the three angles ole a triangle is 2: 3 :4. Find the measure of the largest angle. ​

Answer 1

Answer:

Here's your answer.

Step-by-step explanation:

Let the angle be x.

Sum of all angles of a triangle = 180

2x + 3x + 4x = 9x

9x = 180

x =20

2x = 2 x 20 = 40

3x = 3 x 20 = 60

4x = 4 x 20 = 80.

Hence 80 is the largest angle.

Please mark me as the brianliest.

Answer 2

Answer:

the sum of the angles is supplementary

2x+3x+4x= 180

9x=180

x =180/9

x =20

A=2×20=40

B=3×20=60

C=4×20=80

the largest angle is C =80
