Answer:
Step-by-step explanation
We have given that equation of line a+4b=0
⇒4b= -a
⇒
slope of line =
⇒ is negative therefore it lies into 4th quadrant
By, Pythagoras theorem
by putting value of P= -1 & B=4
the value of
with the given condition
i.e. ∈ (3π/2, 2π)
now,
Answer:
30.1 feet.
Step-by-step explanation:
We have been given that a school flag poll casts a 16 foot shadow on the lawn. A teacher stood at the shadows edge and measure the angle of elevation to the top of the poll at 62°. We are asked to find the height of the tall.
First of all, we will draw a diagram to represent our give scenario as shown in the attachment.
We can see that side length with 16 feet is adjacent side and height of the pole (h) is opposite side to angle of elevation.
We know that tangent relates opposite side of a right triangle to its adjacent side.
Therefore, the poll is approximately 30.1 feet tall.
