Formula to find the central angle is,
Where, s = arc length
r = radius
= central angle in radian.
According to the given problem,
r = 7 and .
First step is to plug in these values in the above formula. So,
By simplifying.
Since
s=14.65
Hence, arc length iss 14.65 feet.
Answer:
Step-by-step explanation:
Observe the given figure.
You can identify that the measure of the angle "B" is:
Knowing this, you can conclude that the angle "p" and the angle "m" are Complementary angles, which means that the sum of their measures is 90 degrees. Then, you can write the following equation:
[Equation 1]
You know that:
Then you can substitute it into the [Equation 1] and then solve for . Therefore, you get:
