Question

the angle of triangle are in the ratio 3:4:5.find the smallest angle in degree and the greatest angle in radians.
​

Answer 1

Answer:

will u plz tell that what is radians?

Answer 2

Answer:

let the ratio be x ...... 3x , 4x , 5x

sum of all angles of ∆ = 180

so,

3x + 4x + 5x = 180

12x = 180

x = 180/12

x = 15

3x = 3×15=45

4x= 4×15=60

5x = 5 ×15= 75

so,

smallest angle = 45°

greatest angle = 75°

$radian \: measure \: = \frac{\pi}{180} \times degree \: measure$

$\frac{\pi}{180} \times 75$

$\frac{15\pi}{36}$

$= \frac{5\pi}{12} radians$
