The angles of a triangle are in the ratio 2/4 / 3 . Find the measure of the greatest angle. a) 60 ° b) 50⁰ c) 40 ° d) 80⁰​

Answer 1

Answer:

80° is the correct answer

Answer 2

Ratio=2:4:3

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

We know,

Sum of measure of angles = 180°

So,

2x+4x+3x=180°

or 9x=180°

or x= 180°/9

or x=20°

Therefore Greatest angle=4x=4×20°=80°

(Note: In the equation , use ‘implies sign’ instead of ‘or’ . I used ‘or’ because ‘implies’ wasn't on keyboard)
