Answer: The height of the telephone pole = $15.046
Step-by-step explanation:
Given: Angle of elevation= 62 degrees.
Distance of Ben from the base of the pole = 8 feet
According to trigonometry, we have
i.e.
Hence, The height of the telephone pole = $15.046
Answer:
Step-by-step explanation:
The opposite side (the one not connected to A) = 4
The hypotenuse is 5
The adjacent side needs to be found for the cosine and the tangent.
a^2 + b^2 = c^2
a = opposite side = 4
b = adjacent side = ?
c = hypotenuse = 5
4^2 + x^2 = 5^2
16 + x^2 = 25
x^2 = 25 - 16
x^2 = 9
x = sqrt(9)
x = 3
cos(A) = adjacent / hypotenuse = 3/5
Tan(A) = opposite / adjacent = 4/3
cos(A) + tan(A) = 3/5 + 4/3
cos(A) + tan(A) = 9/15 + 20/15 = 29/15
Answer:
15
Step-by-step explanation:
Answer:
j=2
Step-by-step explanation:
<em>First, subtract by 5 from both sides of equation.</em>
<em>5-j-5=3-5</em>
<em>Simplify.</em>
<em>3-5=-2</em>
<em>-j=-2</em>
<em>Divide by -1 from both sides of equation.</em>
<em>-j/-1=-2/-1</em>
<em>Simplify, to find the answer.</em>
<em>-2/-1=2</em>
<em>It change negative to positive.</em>
<em>j=2 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
