The length of all the sides is same, if u want to write it as an expression, you can write it as any variable, x,y or z
Answer: 108 degrees
============================================================
Explanation:
Angle ABC is given to be 90 degrees. By the converse of Thales Theorem, we know that AC is a diameter of the circle.
If we draw a line from A to C, it will pass through the center of the circle.
Therefore, arc AC is 180 degrees as this is half the distance around the circle.
minor arc AD = 72
minor arc CD = x
(minor arc AD) + (minor arc CD) = arc AC
72+x = 180
72+x-72 = 180-72
x = 108
minor arc CD is 108 degrees
Since there are 21 questions and one is extra credit, the fraction is 21/20. Divide it to get 1.05. In percent, this is 105%. Hope this helps!

it think it is 2 and 4 if i am wrong i will edit my work
Step-by-step explanation:
Surface area = 2(19 x 15) + 2(15 x 13) + 2(13 x 19)
Surface area = 570 + 390 + 494
Surface area = 1454 cm²
---------------------------------------------
Answer: Surface area = 1454 cm²
