Question

The angles of a triangle are in the ratio 2:3:4. Based on the angles, it is which angles
1)Right angle
2)obtuse
3)acute
4) none
Explain it

Answer 1

Answer:

Acute angle because 20 is less than 90 degree

Step-by-step explanation:

Let the angle be 2x , 3x and 4x

180 = 2x+ 3x +4x

180 = 9x

180÷9 = x

×=20

Answer 2

Answer:

3) acute

Step-by-step explanation:

sum of internal angles in a triangle is 180 degrees

let the value of each angle = x degrees

so 2x + 3x + 4x = 180 where 2x, 3x and 4x are the Values of each angle

9x = 180

x = 20

so the value of all the angles are:

2x = 2 x 20 = 40

3x = 3 x 20 = 60

4x = 4 x 20 = 80

since all thr angles are less than 90 degrees, they are acute angles
