Answer:
−0.171428571 or -6/35
Step-by-step explanation:
This is the Simplest form
Least common denominator is 15, so if you write them both with the denominator 4/5 is 12/15 and 1/3 is 5/15.
recall that a circle has a total of 360°.
so that missing central angle is then 360° - 110° - 65° - 90°. Well, the arc's angle measurement is the same as the central angle they're in, so the x° is the same as 360° - 110° - 65° - 90°.
B.) 22.5 degrees I think is the correct answer.
