Howard is standing 109 yards from the bottom of a water reservoir. He estimates that the angle of elevation to the top of the wa
pav-90 [236]

Answer:

70.1 yards

Step-by-step explanation:

See the attached diagram.

Let AC is the reservoir with A as the bottom and C is the top.

Now, B is the position of Howard which is 109 yards from A i.e. AB = 109 yards.

Again, the angle elevation from B to C is 50 degrees.

So, ∠ ABC = 50°  

Now, \cos 50 = \frac{AB}{BC} = \frac{109}{x}

⇒ x = 109 cos 50 = 70.1 yards.

Therefore, the distance between the top of the reservoir and Howard i.e. BC is equal to 70.1 yards. (Answer)

Taya2010 [7]

Answer:

\left \{ {{x+y=1} \atop {2x+2y=2}} \right.

Step-by-step explanation:

As long as the two equations represent the same straight line on the coordinate plane (they overlap), there will be infinite many intersections and infinite number of solutions.
