Answer:
∠x =
Step-by-step explanation:
Since /BC/ ll /DE/, then ∠CBA = ∠DAB (alternate angles)
Thus,
∠DAB + + x = (sum of angles on a straight line)
⇒ + + x =
+ x =
make 'x' the subject of the formula,
x = -
∴ x =
29
In parallel lines, allied angles have a sum of 180.
Therefore, angle CBD + angle EAB = 180
Therefore, 42 + 109 + x = 180
x + 151 = 180
x = 29
