All sides are equal in an equilateral triangle and the perpendicular bisects the side too.
so BC will be bisected and the segments be 5 each.
you can use Pythagoras theorem to find the altitude length, hypotenuse will be one side of the triangle.

$h^2=100-25=75$
$h=\sqrt{75}=5\sqrt3$
Answer:
3.803% Profit
Step-by-step explanation:
First let us calculate total sales, then calculate the total cost, and then divide the two.

Answer:
x>-2
Step-by-step explanation:
Hi there!
We are given the inequality 7+7(x+4)>21, and we want to solve it
Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.
So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).
7+7x+28>21
Now combine like terms.
7x+35>21
Subtract 35 from both sides
7x>-14
Divide both sides by 7
x>-2
Hope this helps!

Missing number is 288, and the rule is +96
Step-by-step explanation:
First subtract 96 from 192, which is 96
then add that to 192 and the missing value is 288
you should also add 96 to 288 just to make sure it gets you to the last number which is 384.
