Answer:
Step-by-step explanation:
Use Pythagorean theorem,
Base² + altitude² =hypotenuse²
x² + 19² = 21²
x² + 361 = 441
x² = 441 - 361
x² = 80
Answer:
Rotation

Since Joe has 5/6 pounds left and he only needs 1/3 pounds
each day to feed the birds, therefore the number of remaining day’s worth of
seed is:
days = (5/6) / (1/3) = 2.5
The remaining seed can run up to 2 and half days. This also
means that after 2 days, he is remained with ½ of 1/3 pound. ½ of 1/3 pound is
equivalent to 1/6 pound. Therefore the correct rectangle model to use is:
<span>Rectangle
model divided into 3 equal sections, two sections are labeled one-third and one
section is labeled one-sixth, equaling two and one-half days.</span>
There is no picture, but you would substitute the first number for the x and the second for the y
Hey there!
To start, you must use the distance formula which is 
.
x1 and x2 are the x coordinates of the points (it does not matter which one you assign to be x1 and x2) and y1 and y2 are the y coordinates (also does not matter which one you assign to be y1 and y2).
Now, set up your formula and simplify:
= 
≈ 25.0799
