Question

The angles of a triangle are in a ratio of 4:5:3 This triangle will be called as___...Show the working also.

Answer 1

Step-by-step explanation:

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.

Answer 2

Step-by-step explanation:

HEY MATE ......

Angles are in the ratio of 3:4:5

Let the angles be 3x,4x,5x

∴3x+4x+5x=180...........

Sum of the angles of triangleare 180 .

∴12x=180

∴x=15

Hence, the angles are: 45 ∘ ,60 ,75 ∘

hence the triangle is an acute angled triangle
