Step-by-step explanation:

value of d = 90° ( as it's a perpendicular)

e = 49° ( vertically opposite angle)

as, sum of all angles on a straight line is 180°

so,

48° + f = 180°

f = 180 - 49 = 131°

f = 131°

hope this answer helps you dear....take care!

Answer:

d= 90 f = 131 e=49

Step-by-step explanation:

e is equivalent to the opposite angle, hence it will be 49.

f will be equal 180-49, since 49+f=180

d=90 as it completes the right angle opposite to it, d+90=180.
