In traveling across flat land, you notice a mountain a cellular telephone tower is 150 feet tall is placed on top of a mountain that is 1200 feet above sea level. what is the angle of depression from the top of the tower to a cell phone user who is 5 horizontal miles away and 400 feet above sea level?

Step-by-step explanation:

Refer the figure given.

We need to find angle A.

We have AD = 1200 + 150 = 1350 feet

BC = 5 miles = 26400 feet

AB = AD - BD = 1350 - 400 = 950 feet

We have

Angle of depression = 90 - A = 90 - 87.94 = 2.06°

Angle of depression is 2.06°

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
