Question

The angles of a triangle are in the ratio 3:7: 8. Find the greatest and the smallest angles.​

Answer 1

Answer:

Here's your answe

Step-by-step explanation:

Let the three angle be 3x , 7x , 8x

So,

By angle sum property of traingles

3x + 7x + 8x = 180

18x = 180

x = 180/18

x = 10

So , angles are

3x = 3 * 10 = 30degree

7x = 7 * 10 = 70degree

8x = 8 * 10 = 80degree

So,

The grestest angle = 80degree

And

The smallest angle = 30degree

Hope you understand.

Answer 2

let angles A=3x,B=7x,C=8x

sum of triangle=180

3x+7x+8x=180

18x=180

x=180/18

x=10

A=3×10=30

B=7×10=70

C=8×10=80

A is the smallest and C is the greatest angle.
