Variable: r constant: 7 coefficient: -2 and 8
Answer:
34°
Step-by-step explanation:
The angle made when a tangent and a radius intersect=90°
Therefore angle OQP =90°
The triangle made by the two radii is isosceles ( base angles are equal) hence angle POQ=180-2(62)
=56°
The right triangle OPQ can hence be solved as follows
angle POQ=56°
angle OQP=90°
angle x=180-(56+90)=34° as all the interior angles of any triangle add up to 180°
The drain pipe can drain (1/2) of the tank in 1 hour.
The fill pipe can fill (1/6) of the tank in 1 hour.
Working together, the pipes will drain the tank in (1/2) - (1/6) hours.
(1/2) - (1/6) = (3/6) -(1/6) = (2/6) or (1/3) of an hour.
So, working together, it will take 3 hours.

Answer:
The answer to your question is the letter B) 2.6 feet
Step-by-step explanation:
Data
angle = Ф = 78°
Opposite side = 12 ft
Adjacent side = ?
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.
tan Ф = Opposite side / Adjacent side
- Solve for Adjacent side
Adjacent side = Opposite side / tanФ
-Substitution
Adjacent side = 12 / tan 78
-Simplification
Adjacent side = 12 / 4.7
-Result
Adjacent side = 2.55 ≈ 2.6 ft
