Answer:
4.87 ft
Step-by-step explanation:
The height of the skylight =
The height of the blue △ - the height of the red △
Let <em>b</em> ft be the height of the blue △.
sin 60° = 
<em>b</em> = 25 sin 60°
Let <em>r</em> ft be the height of the red △.
tan 40° = 
<em>r</em> = 20 tan 40°
The height of the skylight
= 25 sin 60° - 20 tan 40°
= 4.87 ft (rounded to the nearest hundredth)
Answer:
x = 3.2
Step-by-step explanation:
Because they are similar, the second shape is just a dilation of the first. Because of this, you need to find the scale in which it is dilated.
To do this we would do the following:
(Taking the lengths of the bigger shape divided by the smaller one.)
3 ÷ 2.4 = 1.25
5 ÷ 4 = 1.25
This tells us that the second shape is dilated by a scale of 1.25. Now all we have to do is multiply 4 by this scale to get x.
It looks like this:
4 × 1.25 = 3.2
I hope this helped :)
