To solve this problem, you must know that the measure of an inscribed angle is 1/2 the measure of the arc that it intercepts.

<FNR = 38, and we are trying to find the measure of arc RF (which is the arc that this angle intercepts)

Using the above equation, we know that FNR = 1/2 * RF

or

38 = 1/2 * RF

Therefore when simplified,

RF = 76 degrees

Your answer is the third option, or 76 degrees.

The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean

Marizza181 [45]

Answer:

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

$\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}$
