Answer:
It forms a 90 degree angle
Step-by-step explanation:
Since a circle is 360 degrees, 1/4 of that would be 90.
Cos(x) = BC/AB = 10.5/20 = 0.525 ⇒ x = 58.3°
Step-by-step explanation:
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph.
