Question

The angles of a triangle are in the ratio 3:4:5. find the angle​

Answer 1

Answer. 3x , 4x and 5x respectively. x= 15. ➡Smallest angle in degrees is 45.

Answer 2

Answer:

Let the angles be

3x , 4x and 5x respectively.

Now using the angle sum property of a triangle We have ,

3x + 4X + 5x = 180

12x = 180

x= 180/12

x= 30/2

x= 15.

Hence the angles are

3×15=45

4×15= 60

5×15= 75

→Smallest angle in degrees is 45.

→Greatest angle = 75 .

$radan \: measure = \frac{\pi}{180} \times degree \: measure \\ = \frac{\pi}{180} \times 75 \\ \frac{15\pi}{36} = \frac{5\pi}{12} radians$
