Expert Answer
AB || DC and AC is a transversal.
m
BAC + mACD = 1800 (Sum of Co - interior angle is 1800 )
BAC + mACD = 1800 (Sum of Co - interior angle is 1800 )→mACD = 1800 - 750 = 1050
ACD = 1800 - 750 = 1050 mECF =mACD = 1050 ...(vertically opposite angles)
ECF =mACD = 1050 ...(vertically opposite angles) In ΔCEF,
ECF + E + F = 1800 (Sum of all the three angles of a triangle is 1800)→ 1050 + x + 300 =1800
→ x = 450
