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°
Answer:

Step-by-step explanation:
We convert some numbers to decimal fractions:
-2 = -2.00
-3/4 = -0.75
-0.45
3% = 0.03
0.36
We order
-2, -0.75, -0.45, 0.03, 0.36
