Question

Find the value of x. 45 60 90 80

Answer 1

Answer:

Step-by-step explanation:

The formula you want is x°=$\frac{1}{2}$(major arc - minor arc)

If the minor arc is 90, and all the way around the outside of a circle is 360 degrees, that means that the major arc measures 360 - 90 = 270.  Filling in our formula:

x°=$\frac{1}{2}$(270 - 90)

or

x° = $\frac{1}{2}$(180)

That gives us that x is a right angle at 90°
