DiKsa [7]

Answer:

angle f = 147 degree and angle e = 33degree

Step-by-step explanation:

here,

angle d= 147 degree

angle f = ?

angle e= ?

we know that,

angle d= angle f (Being alternate angle always be equal.)

or, 147 degree = angle f

Hence, angle f is 147 degree.

And,

angle d sum angle e= 180 degree(being cointerior angle)

or, 147 degree add angle e=180 degree

or, angle e= (180-147) degree

or, angle e= 33 degree

Hence, angle e is 33 degree.

so, angle f=147 degree

angle e= 33 degree

ANS

angle e= 33 degree
