Question

If the angleof a triangle are in the ratio 1:4:7, then the vaule of the largest angle is :

Answer 1

Take a value x

So the angles must be 1x,4x,7x

Thus we know that the sum of the angles in a trianle is 180

1x+4x+7x=180

12x=180

x=15

So the largest angle is 7x=7×15=105

Hope it helps you

Answer 2

Answer:

105

Step-by-step explanation:

Take a value x

So the angles must be 1x,4x,7x

Thus we know that the sum of the angles in a trianle is 180

1x+4x+7x=180

12x=180

x=15

So the largest angle is 7x=7×15=105
