Question

the sum of two angle is 80 grades and their difference is 18degree.find the angle???

Answer 1

Let two angle be x and y
So
x+y=80
x-y=18
2x=98
x=44

44-y=18
44-18=y
26=y

Answer 2

Answer:

let two angels be x and y.

Step-by-step explanation:

x+y=80 ............ equation 1

x-y=18 .............. equation 2

=2x=98

x=98/2=49 degree

put value of x in eq.1

49+y=80

y=30 degree

x=pie/180×x radians.

x=pie/180×49=49pie/180

49/180×22/7=77/90=0.855 radians

y=pie/180×31=31pie/180

31/180×22/7=341/630=0.55 radians
