A sequence of operations that will get you to the solution is ...

... d. multiply each side by-5, add 25 to each side

_____

That is not the only correct sequence of operations. However the other ones listed here are incorrect ways to get to x = -10.

You can do whatever multiplication and addition you like to each side of the equation, but if those operations are poorly chosen, they will make finding the solution more difficult.

The measure of the angle of depression from the top of a 270 m building tweet park bench on the ground is 63° 43’.How far Where

Norma-Jean [14]

Answer:

547 m

Step-by-step explanation:

Given :

Angle of depression, θ = 63°43' ; 43/60 = 0.7167 = 63 + 0.7167 = 63.7167°

The height, h = 270

The distance of park bench from the building, d is given by :

Tan θ = opposite / Adjacent

Tan 63.7167 = d / 270

d = 270 * Tan 63.7167

d = 546.70459

d, distance of Park bench from building is 547 m
