Try doing the rest. I'll start the problems. All you have to do is solve. Don't forget to label!
41. 25 x 25 ÷ 3
42. (20 x 21 ÷ 3) + (15 x 21)
43. (120 x 60) + (80 x 140 ÷ 3)
The answer is c=50.272, for other problems like this use the formula: The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).

Answer:
(b) 48
Step-by-step explanation:
In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.
x = √(36·64) = √36×√64 = 6×8
x = 48
_____
All of the triangles are similar, so the ratios of corresponding sides are the same.
short side/long side = x/64 = 36/x
x^2 = (64)(36) . . . . as above
Answer:
They are both 45 degrees
Step-by-step explanation:
The square in the middle means a right angle (90) and 5 and 6 are equal too so they both equal 45
