The angle of depression from the top of a flag pole to a point on the ground is 30°. If the point on the ground is 75 feet from

Cerrena [4.2K]

Answer:

Height of flag pole to the nearest foot is 43 feet

Step-by-step explanation:

In the diagram we have flag pole AB and C is the point on the ground.

It is given that angle of depression is 30°

and the distance of the point C from the base B is 75 feet

so we have

BC= 75 feet

∠C = 30°

AB= h feet

now in right ΔABC

$tan C = \frac{opposite \ side }{base} \\tan C=\frac{AB}{BC}$

now we plug AB= h , ∠C= 30° and BC =75

$tan 30= \frac{h}{75}$

$75 tan30 = h$ ( multiply both sides by 75)

$h= 75 tan 30 =75 (0.5773)\\ h= 43.3 feet\\$

Height of flag pole to the nearest foot is

h= 43 feet

ehidna [41]

Answer:

see below

Step-by-step explanation:

A = 1/2 b*h

A = 1/2 (5*7)

We can use the commutative property of multiplication which states

a*b = b*a

A = 1/2 (7*5)

This will not affect the answer because 5*7 = 7*5
