Question

The angles of a triangle are in the ratio 3,2,7 find each angles

Answer 1

Answer:

Step-by-step explanation:

Let all the angles be 3x ,2x ,and 5x

So, 3x+5x+2x = 180° ( triangle sum property)

10x = 180°

x = 180°/10 = 18°

Now , all angles are

2x = 2×18 = 36°

3x = 3×18 = 54°

5x = 5×18 = 90°

Answer 2

Step-by-step explanation:

Given, The ratio of the angles of a triangle = 3:2:7

Suppose; The 1st angel is = 3x

The 2nd angel is = 2x

The 3rd angel is = 7x

Then; Total of the angel are = 3x + 2x + 7x = 12x

We know; The total of the angels of a triangle = 180°

According To The Question,

12x = 180 ; x = 180 ÷ 12 = 15

So, The 1st angel is = 3 × 15 = 45°

The 2nd angel is = 2 × 15 = 30°

The 3rd angel is = 7 × 15 = 105°
