Answer:
m∠BCD = 140°
Step-by-step explanation:
ABCD is cyclic quadrilateral. A property of cyclic quadrilateral states that the opposite angles of it sum up to 180°. Here:
m∠A + m∠C =180° and m∠B + m∠D = 180°
So, m∠A + m∠C =180°
m∠A = 40° (given in the question)
40° + m∠C = 180°
m∠C = 180° - 40° = 140°
∴m∠C = m∠BCD = 140°

35 tickets for gals @ $1 = $35
Total = 55 tickets and $75</span>
2/5 + 2/4 = 8/20 + 10/20 = 18/20 = 9/10
Answer:
48
Step-by-step explanation:
The formula for finding the area of a rectangle is: l * w = a
So 12*4 = 48.
