Answer: x = 90</h3>
============================================
Explanation:
The arc measure is some unknown number x, so is the angle formed by the tangents that form based on this arc. The arc and angle add to 180, so,
x+x = 180
2x = 180
2x/2 = 180/2
x = 90
A right angle forms if we were to draw segments from the center of the circle to the points of tangency. We have a square forming if we do so. Recall that the points of tangency have the radius and tangent segments meet up at a 90 degree angle.
Answer:
c
Step-by-step explanation:
Because, when you divide you can use place value to break the equation up and make it easy. Example: 142/2. 140/2=70 and 2/2=1 add 70 +1=71. So 142/2=71
