A^2 + b^2 = c^2....this is the pythagoream theroum (sorry, probably spelled it wrong)....it is used for right triangles.
a and b are ur legs of the triangle and c is the hypotenuse. Therefore, the value of a^2 is the value of one of the legs, squared.
OR. if u mean this..
a^2 + b^2 = c^2
a^2 = c^2 - b^2
Answer:
<u>After July, Ana's monthly salary was $1920</u>
Step-by-step explanation:
In May, Ana's monthly salary was $2000. During the next month, the salary increased by 20%, or (0.2)(2000)
So, in June, Ana's monthly salary was $2400. During the next month, the salary decreased by 20%, or (0.2)(2000)
Therefore, after the two changes, Ana's monthly salary was <u>$1920</u>
Answer:
radius = 21
circumference = 138.88
Step-by-step explanation:
First divide the area by 3.14, this equal 441
441 is your radius squared.
Then you have to find the root of 441 which is 21.
radius = 21
diameter = twice the radius or 2 * radius
diameter = 21 * 2 = 42
diameter = 42
Then plug 42 in your circumference formula.
Which is then C = 3.14(42).
Which means the circumference is 131.88.
