Question

in a right angled triangle A BC right angled at B and A^ = 30 degree then find the value of C^

Answer 1

hey...

sum of angles in a triangle = 180°
A + B + C = 180°
30° + 90 + C = 180°
120° + C = 180°
C = 180° - 120°
C = 60°

Answer 2

in triangle ABC,
angle a =30
and, b = 30 then,
angle a+b+c =180 degree
30+30+c=180
60+c =180
c= 180-60=120

Hope my answer is right.......
Thank you.....
