A) Work out the size of angle x.

b) Give reasons for your answer.

angle x = angle f (corresponding Angles )

angle f + 105 degrees = 180 degrees ( linear pair )

since angle f = x

angle x + 105 = 180

x = 180 - 105

x = 75 degrees

hopes this helps u

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
