For the first problem, the answer is B. For the second problem, the answer is A.
From the figure, m<ACD = m<ABD
4x + 4 = 6x - 14
6x - 4x = 4 + 14
2x = 18
x = 9
Therefore, m<ACD = 4(9) + 4 = 40°

I had the same question I got it right
180 -134 = 46 is PRQ
46 x 2 = 92 is POQ acute angle
360 - 92 = 268 is POQ reflex angle
Answer:
See below in bold.
Step-by-step explanation:
The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).
So the area of one piece = 1/2 * 9 * 40 cm^2.
The total amount of cloth required for one umbrella = 10 * 1/2 * 9 * 40
= 1800 cm^2.
The total cost = 1800 * 0.25 = Rs 450.
