Question

If the sum of 2 angles is equal to third angle and difference between them is 50 degree then find third angle?

Answer 1

a+b = c

given that ==> a+b = c

we know that a+b+c = 180

(a+b)+c = 180

==> putting the value of c

==> c+c = 180

==> 2c = 180

==> c = 90

==> A+B = 90

and given difference = A-B = 50

SO, A+B = 90

      A-B = 50

==> 2A = 130

==> A = 65

PUTTING VALUE IN EQ(1)

==> A+B = 90

==> 65+B = 90

==> B = 25

I HOPE ITS HELPFUL
