The questions are illustrations of trigonometry ratios and right triangles
- The value of x is 11.8310
- The tree is 23.3154 feet tall
- The depth of the sub is 376.7770 meters
Trigonometry ratio
Trigonometry ratios are very useful in determining the measure of angles, and the side lengths of a right triangle.
<h3>Question 1</h3>
The value of x is calculated using the following sine trigonometry ratio

Make x the subject

This gives

Hence, the value of x is 11.8310
<h3>Question 2</h3>
This question is illustrated by the first diagram in the attached figure
The height (h) of the tree is calculated using the following tangent trigonometry ratio

Make h the subject

This gives

Hence, the tree is 23.3154 feet tall
<h3>Question 3</h3>
This question is illustrated by the second diagram in the attached figure
The depth (h) of the sub is calculated using the following tangent trigonometry ratio

Make h the subject

This gives

Hence, the depth of the sub is 376.7770 meters

Answer:
When you divide fractions, you multiply by the reciprocal, So, you would have 9/5 * 15/14 you can cancel,  and get 9/1 * 3/14, and end up with 27/14, 
 
        
             
        
        
        
Answer:
Option C
Step-by-step explanation:
The given function is:  .
.
  .
.
  .
.
The average rate of change of this function on the interval t=3 to t=5 is given by:


Since the average rate of change is negative on the interval 3-5 seconds, it means the ball is moving downwards at an average rate of 48 feet per second.
The correct choice is C.
