Answer: True</h3>
Explanation:
A rectangle has all four angles that are 90 degrees. The side lengths may or may not all be the same length; however, we do know that the opposite sides are the same length.
A square is a special type of rectangle where all four sides are the same length and all angles are 90 degrees.
If a figure is a square, then it is automatically a rectangle, but not the other way around.
Answer:
Surface area is 66 units.
Step-by-step explanation:
I calculated the area of each rectangle in the net.
3 x 7= 21
3 x 7= 21
2 x 3= 6
2 x 3= 6
2 x 7= 14
21 + 21 + 6 + 6 + 14 = 66
We want to find miles per gallon. Another way of saying miles per gallon is miles/gallon. So we will plug the numbers into this equation:
60 miles/3 gallons = 20 miles/gallon
This is because 60/3=20.
I hope this makes sense.
22? (Correct me if I’m wrong)
Answers:
x = 2√2 units
y = 2√6 units
Explanation:
The given diagram is a right-angled triangle. This means that the special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
For getting x and y, we can choose to either work with θ = 30 or θ = 60.
I will work with 30.
1- For x:
We have:
θ = 30
x is the opposite side to θ
4√2 is the hypotenuse
Therefore, we can apply the sine function as follows:
sin θ = opposite / hypotenuse
sin (30) = x / 4√2
x = sin (30) * 4√2
x = 2√2 units
2- For y:
We have:
θ = 30
x is the adjacent side to θ
4√2 is the hypotenuse
Therefore, we can apply the cosine function as follows:
cos θ = adjacent / hypotenuse
cos (30) = y / 4√2
y = cos (30) * 4√2
y = 2√6 units
Hope this helps :)
