What is the actual height of the building shown in the model?

julsineya [31]

Answer:

The actual height is 150ft

Step-by-step explanation:

Given

$Width : Height = 2cm : 5cm$

$Actual\ width = 60ft$

Required

Determine the actual height

Substitute 60ft for width in: $Width : Height = 2cm : 5cm$

$60ft:Height =2cm:5cm$

Express as fraction

$\frac{60ft}{Height} =\frac{2cm}{5cm}$

$\frac{60ft}{Height} =\frac{2}{5}$

Make height the subject

$Height = \frac{5}{2} * 60ft$

$Height = 5 * 30ft$

$Height = 150ft$

You want to find the area of the circle. The formula for the area of a circle is A=πr^2 (Area=pi times radius squared). The diameter is the distance across the circle. Radius is half the diameter. Diameter=3. 3 divided by 2 equals 1.5. So, plug it into the equation. A=π1.5^2 (Area=pi times 1.5 squared).

$m\angle LKJ=360-m\angle KJM-m\angle JML-m\angle MLK\\
m\angle LKJ=360-132-48-m\angle MLK\\
m\angle LKJ=180-m\angle MLK\\\\
m\angle MLK=180-m\angle KLN\\
m\angle MLK=180-150\\
m\angle MLK=30^{\circ}\\\\
m\angle LKJ=180-30\\
\boxed{m\angle LKJ=150^{\circ}}$
