Answer: 20, I believe
Step-by-step explanation: You already have 500 which is half of 1000. 500 divided by 25 equals 20.
b. c=4s
you multiply x times 4 to get y
Two congruent parts mean the two parts you have are the same or they are equal to eachother.
The 29 degree angle and the angle x are complementary; that is, they sum up to 90 degrees. Thus, x + 29 = 90, and x = 61 (degrees).
