Heya !

Hope it helps you ;)
the angle with the equation (9x+11) is a vertical angle with the 56 degree angle.
This means the two angles are the same.
Set the equation to equal 56 and solve for X:
9x+11 = 56
Subtract 11 from each side:
9x = 45
Divide both sides by 9"
x = 45/9
x = 5
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
