Answer:
d= 90 f = 131 e=49
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.
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!
