Question

The angle of a triangle are in the ratio 5 : 3 : 7, the triangle is

Answer 1

Answer:

Step-by-step explanation:

The angles of a triangle are in the ratio 5:3:7

Let these three angles be 5x°,3x°,7x°

By condition,

5x°+3x°+7x° = 180°

5x+3x+7x = 180

15x = 180

x = 180/15

x = 12

The angles are

(5×12)°=60°

(3×12)° =36°

(7×12)° =84°

After observing the angles we conclude that the triangle is A. an acute angled triangle

Answer 2

SOLUTION

GIVEN

The angle of a triangle are in the ratio 5 : 3 : 7

TO DETERMINE

The type of the triangle

EVALUATION

Here it is given that the angle of a triangle are in the ratio 5 : 3 : 7

Let the angles are 5x , 3x , 7x

Since sum of three angles of a triangle is 180°

So by the given condition

5x + 3x + 7x = 180°

⇒15x = 180°

⇒ x = 12°

So the three angles are 60° , 36° , 84°

Since all the three angles are less then 90∘

Therefore the triangle is an acute angled triangle
