Question

5.
If the angles of a triangle are in the ratio2:3:7 then the largest angle is ​

Answer 1

Explanation:

Let the angle of triangle be 2x , 3x , & 7x

By angle sum property:-

2x+3x+7x=180

∘

⇒12x=180

∘

⇒x=15

2x=2×15=30

∘

3x=3×15=75

∘

7x=7×15=105

∘

Then the largest angle is 105

Answer 2

Answer:

105

Explanation:

let the angles be 2x, 3x 7x

acc. to sum angle property

2x + 3x + 7x = 180°

12x = 180°

x = 180/12 = 15°

Therefore the angles are

2x = 2(15) = 30°

3x = 3(15) = 45°

7x = 7(15) = 105° ( THE LARGEST ANGLE)
