Question

In the adjacent fig. AB and AC are opposite rays if A-B=20° find A and B

Answer 1

Hey mate !!!

here is your answer !!!

given A- B = 20 ° ----------(1)


but

A + B = 180 ° ( straight line ). --------(2)


from equation 1 and 2 we get


A-B= 20 °

and A +B = 180°


on SOLVING

we get , 2A = 200

hence , A = 100 °


now ,
put the value of A in equation 1

hence the value of B = 80°

hence , A = 100° and B = 80°


hope it helps you dear !!!


thanks !!!
