Answer: 12.5
Step-by-step explanation: The triangle ABC and its altitude is represented in the figure below.
<u>Altitude</u> is a segment of line that link a vertex and the opposite side, forming a right angle.
So, because of , now we have two similar triangles, which means that ratios of corresponding sides are equal:
(1)
This is always true for a right triangle and a altitude drawn to the hypotenuse.
Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.
(2)
Substituting (2) into (1):
We want to find f, so:
f = 7.5
The length of is
The length of the hypotenuse of triangle ABC is 12.5 units.
Answer:
x = 5
Step-by-step explanation:
A = hb/2
10 = 4(x)/2
10 = 2x
x = 5
im not sure if this is right but get back to me if it isn't
Answer: 8π mm (in terms of π)
Step-by-step explanation:
1) The formulas for solving the circumference of a circle is πd (π times diameter).
2) 8 times π equals 8π mm.

Answer:
n=150+20m
Step-by-step explanation:
we don't know how many months they're charging for, so we don't know the total of the amount.
