4) 62.8 cm^2
5) It is quadrupled
Answer:
<h2>
40.1 cm</h2>
solution,
BC=8.4 cm
AB=12 cm
BD=4.1 cm
We have to find out: AC ,CD
using Pythagoras theorem:
In ∆ABC ,<B=90°

Similarly,
In ∆BCD, CB=90


Perimeter:
AC+CD+AD
=14.64+9.34+(12+4.1)
=40.08
= 40.1 cm
Hope this helps...
Good luck on your assignment..
Answer:
See below ~
Step-by-step explanation:
x-values :
- Lowest : 2
- Highest : 10
- Lies between 2 and 10
y-values :
- Lowest = 4
- Highest = 11
- Lies between 4 and 11
Answer:
1400 ft^3
Step-by-step explanation:
Volume of a box is given by
V = l*w*h
= 10*5*28
=1400 ft^3
Answer:
x = 17
, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° =
, tan30° = 
sin30° =
= 
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y =
= 34
tan30° =
= 
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x =
= 17
