Answer:

Step-by-step explanation:

3x - 15 = x + 33 [sides opposite congruent angles in a triangle are congruent]
2x - 15 = 33 [subtract x from both sides]
2x = 48 [add 15 to both sides]
x = 24 [divide both sides by 2]
BC = 24 [BC = x]

Answer:

787.5 cm^2.

Step-by-step explanation:

This consists of a parallelogram and a trapezium.

Area of parallelogram = 23 * 14 cm^2.

Area of the trapezium = 1/2 * (19) * ( 15 + 34)

Total area = 23 * 14 + 1/2 * 19 * 49
