I don't think anyone can solve this without seeing the table mentioned in the question :)
36.91 is the answer 67.1x.55
Answer:
62°
Step-by-step explanation:
Since one arm making angle x is diameter. So, by inscribed angle theorem, we have:

Answer:
23.3
Step-by-step explanation:
Use phyth. Thm.
a^2 + b^2 = c^2
A and B are the side lengths, and C is the hypotenuse. The hypotenuse is across the right angle.
Since you only have one side length and the hypotenuse this what your equation will look like:
30^2 + x^2 = 38^2
900 + x^ = 1444
544 = x^2
x = roughly 23.3
