WILL GIVE BRAINLIEST The angle of elevation from Ben to the top of a telephone pole is 62 degrees. If Ben is standing 8 feet fro
MrRissso [65]

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

\tan x=\dfrac{\text{side opposite to x}}{\text{side adjacent to x}}

i.e.

\tan 62^{\circ}=\dfrac{\text{ height of the telephone pole}}{8}\\\\(1.880726)=\dfrac{\text{ height of the telephone pole}}{8}\\\\\text{ Height of the telephone pole} = 8\times 1.880726\approx15.046

Hence, The height of the telephone pole = $15.046

Sin A 4/5.<br><br> Find<br> COSA + tan A
Ivahew [28]

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

What is 5 - j = 3 ????
VikaD [51]

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>
