Answer:
Measure of angle O is 56 degrees.
Step-by-step explanation:
We can see from diagram that NQ is minor arc and NRQ is major arc. Our angle R (inscribed angle) and O (central angle) are corresponding to minor arc NQ. We will use inscribed angle theorem which states that measure of inscribed angle is one-half the measure of central angle.
We are given that measure of inscribed angle R is 28 degrees. To find measure of our central angle O we will multiply 28 by 2.
Therefore, measure of angle O will be 56 degrees.
Answer:
r=3
Step-by-step explanation:
- The equation of a circumference is
.
- Then , in this case
, and then to know the value of r we just simply have to calculate the square root of 9, which is 3.
