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.
$h^2=100-25=75$
$h=\sqrt{75}=5\sqrt3$
8.2
3 does not add 1 to 2 so it's 8.2
It has to be 438 because any number that is 5 or higher must be rounded up so 438 could be rounded up to 440
950 * .05 = $47.5
550 * .04 = $22
$47.5 + $22 = $69.50 interest earned
answer: amount in 4% account = $550
