Answer:
the answer is 5
Step-by-step explanation:
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
Answer:
Step-by-step explanation:
With two congruent sides the third side is greater against a greater angle.
<u>34 < 36, therefore:</u>
<u>And, the angle should have a positive value:</u>
<u>Combined, we get:</u>
The length is going to be 15.5. Please message me if you want the explanation
The answer:
First: sec(-pi) is sec(pi)
And sec(pi) is -1
