Answer:
The angle of elevation to the top of the mast is 23.82°
Step-by-step explanation:
Given as :
The length of the rope = 37.13 foot
The length of the mast = 15 foot
Let the angle of elevation to the top of the mast = Ф
So, Sin angle = 
Or, Sin Ф = 
or, Sin Ф = 
or , Sin Ф = 0.40398
∴ Ф = 
0.40398
or, Ф = 23.82°
Hence The angle of elevation to the top of the mast is 23.82° Answer
Answer:
C) 55 degrees
Step-by-step explanation:
You need the following geometry definition.
<u><em>Definition:</em></u>
<em>The measure of an arc of a circle is equal to the measure of the central angle that intercepts it.</em>
Angle AOB is a central angle since its vertex is the center of the circle.
According to the theorem above, the measure of arc AB is the same as the measure of central angle AOB.
measure of arc AB = measure of angle AOB
measure of arc AB = 55 degrees
Answer: C) 55 degrees
Answer:
4
Step-by-step explanation:
Is the Square Root of 225 Rational or Irrational? 225 can be expressed as the ratio of two integers. As 225 can be expressed as 225 = 225/1. Thus 225 is rational.
