Step-by-step explanation:
c is the only one where the results are truly random
sorry don't really know how to explain it rather than looking at the definition
I hope this helps you
sin23=5/13
So the equation you would make is 63 / 9 = width
This is because the formula of finding the area of a rectangle is <em>l </em>x <em>w = a</em>.
So since we already know the length and area, we just plug them in and switch up the formula to find the width.
If 9 (length) x ? (width) = 63 (area), then 63 / 9 = ? (width)
If you calculate it in your mind or even a calculator, you will find that 63 / 9 = 7.
Therefore the width of the rectangle is 7.
Answer:
180
Step-by-step explanation:
17 yards. The fence that enclose Sondra's backyard is a right triangle whose sides measuring 8 yards, 15 yards and 17 yards respectively.
The key to solve this problem is using the Pythagorean Theorem that dictates; In every right triangle the square of the hypotenuse is equal to the sum of the squares of the legs and the equation hypotenuse²=leg1²+leg2².
For this problem we know the measuring of two side, which mean that we can apply Pythagorean Theorem equation as follow:
Let's say that one of the side is a = 8yards, and the other side is b = 15yards. So, we want to know how long the third side c long.
Applying the Pythagorean Theorem:
Substituting the values of the sides a and b:
