Question

Please Explain step by step

Answer 1

Ans:- Given:-

1. L || m || n

2. A = 105°

3. mBc = 35°

to find,

x, y = ????

Solution:-

l || m

so, mBC = y (alternate angle are equal)

=> 35° = y

=> y = 35°

Now,

=> A+x = 180°(sum of co-interior angle is 180)

=> 105+ x = 180

=> x = 75°

here is your answer

hope it will help you
