Look at the picture.
The union of two sets A and B (A ∪ B) is the set of elements which are in A, in B, or in both A and B
The path between three landmarks in a national park form a right triangle. The oldest living evergreen tree is at point A, the
ranger station is at point B, and the natural hotspring is at point C. The right angle is at point C, and there is a 60degrees angle at point B. If the distance between the hotspring and the evergreen tree is 601 yards, find the distance, x, from the hotspring to the ranger station.

Answer:
<h2> A. 40°</h2>Step-by-step explanation:
AO = CO = radius
AO = CO ⇒ AB = BC and m∠AOB = m∠BOC = ¹/₂m∠AOC
From BDOE:
m∠EOB + m∠OBC + m∠CDE + m∠DEO = 360°
(65° + 75°) + 90° + x + 90° = 360°
140° + 180° + x = 360°
x = 40°
