The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The distance from point C to point D is 258.8 meters.
<h3>What is Tangent (Tanθ)?</h3>The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The distance from point C to D is equal to the distance from point A to B. Therefore, the height of the building can be written as,
Tan(25°) = AB / BC
Tan(25°) × 555 m = AB
AB = 258.8 meters
Hence, the distance from point C to point D is 258.8 meters.

Answer:
22.4 hours
Step-by-step explanation:
The population of bacteria is modelled by the equation:
From the the question, the initial population of bacteria is 720.
So after 26 hours, we have:
This implies that:
We want to find how long it will take for there to be 1310 bacteria present.
To the nearest tenth , it will take 22.4 hours
