Answer:
5=135
7=45
Step-by-step explanation:
Set them equal to 180. So i started plugging in numbers and subtracting them by 90. Then add it back to the number until i got 180.
<u>The apothecary system</u><u> uses the minim as the basic unit of liquid measure and the grain as the basic unit of solid measure.</u>
What is apothecary measurement?
- The apothecary system was once a system of weights and measurements used for drug prescription and dispensing.
- A pound was divided into 12 ounces in the English version, which also divided an ounce into eight drams or drachms and a dram into three scruples, or 60 grains.
What are the units of the apothecary system?
The grain, scruple (20 grains), dram (3 scruples), ounce (8 drams), and pound—a ancient scale of weight used in the British Isles for measuring and distributing pharmacological goods (12 ounces).

You can check your factoring by multiplying them all out to see if you get the original expression. If you do, your factoring is correct; otherwise, you might want to try again
Answer:
A)4
Step-by-step explanation:
Assuming all edges are integral values
The most basic right angles triangle with integral edges is
(3,4,5)
as it obeys pythogores theorem
which is
![a^{2}+ b^{2} =c^{2} \\\text{where c is the hypotenuse}\\\text{and a and b are the other side}](https://tex.z-dn.net/?f=a%5E%7B2%7D%2B%20b%5E%7B2%7D%20%3Dc%5E%7B2%7D%20%5C%5C%5Ctext%7Bwhere%20c%20is%20the%20hypotenuse%7D%5C%5C%5Ctext%7Band%20a%20and%20b%20are%20the%20other%20side%7D)
![3^{2} +4^{2} =5^{2}](https://tex.z-dn.net/?f=3%5E%7B2%7D%20%2B4%5E%7B2%7D%20%3D5%5E%7B2%7D)
Now, double each edge,it will still remain a right angled triangle since it will still obey pythogores theorem
so the edges are (4,6,10)
⇒4 cm is the short leg of a integral right triangle with hypotenuse 10 cm
