Hello,

Let's assume a the hypotenuse

b/a=sin 30°==>b=a/2

On a scale drawing,1 in represents 8 feet. What is the actual length of a room that measures 3.4 inches

Xelga [282]

Answer:

27.2 ft

Step-by-step explanation:

Since 1 in on the drawing = 8 ft, we should find out how much ft is 3.4 in.

So, to get from 1 to 8, we multiply by 8.

And since we multiply by 8, we also have to do it to the other part as well.

So we would do:

8 x 3.4 = 27.2

Hope this helps! :)
