Question

6. The angles of a triangle are in the ratio 5:37. What is the type of the triangle.​

Answer 1

Answer:

Angles of triangle are in the ratio 5:3:7

Therefore,

5x+3x+7x=180

o

15x=180

o

x=12

o

5x=5×12=60

o

3x=3×12=36

o

7x=7×12=42

o

Since ,all angles are less than 90

o

Therefore, the triangle is an acute angled triangle.

$\:$

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

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

$\:$

By Angle sum property :-

5x+3x+7x=180

15x=180

x=12

Thus, angles are, 60∘, 36∘ ,84∘

Since, all the angles are less than 90∘

it is an acute angled triangle.
