A traffic camera sits on top of a tower that has a height of 39 ft. The angles of depression of a car on a straight road at the same level as that of the base of the tower and on the same side of the tower are 31°. Calculate the the distance between the base of the poll and the car. Round to the nearest tenth of a foot. *
1 answer:
Answer:
48ft
Step-by-step explanation:
<u>Distance of car A from the tower</u> Consider ∆ACD
tan25 = 50/AC
AC = 50/tan25 = 50/0.4663 = 107.2 ft
<u>Distance of car B from the tower</u> Consider ∆BCD
tan40 = 50/BC
AC = 50/tan40 = 50/0.8391 = 59.6 ft
<u>Distance from cars A and B</u>
AB = AC – BC = 107.2 – 59.6 = 48 ft
The distance between the two cars is 48ft

<span>Y DO I W? (Why do I double you?)
Answer:
y + 7 = -1/4(x - 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -1/4
Point (4, -7)
<u>Step 2: Write Function</u>
y + 7 = -1/4(x - 4)
Answer:
2500
Step-by-step explanation:
there you go haha
The point-slope form:
m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).
