A building 220 feet casts a 100 foot long shadow. If a person stands at the end of the shadow and looks up to the top of the bui
kaheart [24]

Answer:

65.56°

Step-by-step explanation:

= We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

Opposite = 220 feet = Height of the building

Adjacent = 100 feet = Length of the shadow

Hence,

tan θ = 220/100

tan θ = 2.2

= arctan(2.2)

= 65.55604522°

Approximately = 65.56°

Someone anybody please help

This is a system of equations problem that can be solved using one of three methods: <span>graphing, substitution, or <span>elimination. I'll be using substitution.

In substitution:
1) S</span></span><span>olve one equation for either variable. I'll use the first equation because its easier to solve for one of the variables. I'll be solving for y because that will allow us to solve for the value of x faster.
</span>x+y=60
y=60-x

2) Substitute what you get into the other equation:
20x + 5y = 600
20x + 5(60-x) = 600

3) Solve your new equation in step 2 for the variable, x.
20x + 5(60-x) = 600
20x + 300-5x = 600
15x + 300 = 600
15x = 300 
x=20

There are D) 20 $20 bills in her drawer.
