plzz answer this question in brief....​

Answer 1

Answer:

a= 105° and b= 75°

Step-by-step explanation:

Given, a is greater than b by 1/6th of a straight angle.

ie a= b+ 180/6

a= b + 30............ equation (1)

We know, angle made with straight line is of 180°.

a + b= 180°........... equation (2)

put eqn (1) in (2)

we get

b + 30 + b= 180

2b= 180 - 30

2b= 150

b= 75°

keep this b=75 in equation (2)

a + 75 = 180

a= 180- 75

a= 105°

This is the required answer.
