Question

the angles of a triangle are in the ratio 3 : 5 : 7 find the measure of each angle of the triangle​

Answer 1

Step-by-step explanation:

Let the angles of triangle be 3x ,5x ,7x

Sum of triangle=3x+5x+7x

180°=15°x

180÷15=x

12=x

So, 3×12=36°

5×12=60°

7×12=84°

Answer 2

Step-by-step explanation:

Let the 1st angle b 3x.

2nd be 5x.

3rd be 7x.

According to angle sum property of triangle

Angle 1 + angle 2 + angle 3 = 180°

3x + 5x + 7x = 180°

15x = 180°

x = 180°/15

x = 12

____________________

Therefore,

1st angle = 3x = 3 × 12 => 36°

2nd angle = 5x = 5 × 12 => 60°

3rd angle = 7x = 7 × 12 = 84°
