Question

the sum of 2 angles is 5 pi radian and their difference is 60 degree find angles in degree

Answer 1

to convert radian to degree

radian×180°/π

5π×180°/π= 900°

x+y=900°----(1)
x-y=60°----(2)

(1)+(2)
2x=960°
x=480°

x value substitute in (1)
y=420

Answer 2

Hey buddy here is ur answer .....


We have to convert radian to degree

so , Radian × 180/pie = 900

According to question ,


x + y = 900 ---------(1)
x - y = 60 ----------- (2)

Now by adding (1) and (2)

2x = 960
x = 480


Hence by substituting the value of x in eq (1)


we will get ,

y = 420 .....




hope u got the concept .....
