Question

The angle of a triangle are in the raton 5:3:7 the triangle is.
(a) An acute angle triangle
(b) An obture angle triangle
(c) An right angle triangle
(d) An isosceles triangle​

Answer 1

Answer:

let the ratio be 5x,3x and 7x

then,

5x+3x+7x=180°

15x=180°

x=180/15°

x=12°

5x=5*12=60°

3x=3*12=36°

7x=7*12=72°

option (a)

Hope it was helpful to you.

Answer 2

Step-by-step explanation:

LET THE ANGLES BE 5x+3x+7x

So= 5x+3x+7x =180°

= 15x = 180°

x= 180/15=12

5 x 12 = 60°

3 x 12 = 36°

7 x 12 = 84°

So, therefore the angle is " ACUTE ANGLED TRIANGLE"
