Question

find the measure of the unknow angle ​

Answer 1

Answer:

105 is the correct answer

Answer 2

Answer:

x = 105°

Step-by-step explanation:

As a || b

so line b is a straight line so it wholly substends an angle of 180°

Given half angle if b is 75 so remaining half will be 180 - 75 = 105°

as a || b so x angle corresponds to 105° angle

So x = 105°
