So, what you’re doing here is basically finding the measurements of a right triangle, so we’ll use the formula
a^2+b^2=c^2
now, we plug in what we have
12^2+x^2= 19^2
144+x^2= 361
Bring the variable to one side by subtracting 144 from each side
x^2= 217
Square root each side to get rid of the exponent on the x
x= 14.7309
ANSWER:
15 inches
These sides will form a triangle because the longest side (302) is less than the sum of the other 2 sides. http://www.1728.org/trianinq.htm
Using Heron's formula, we first have to determine the semi-perimeter of the triangle. (perimeter divided by 2)(240 + 121 + 302) / 2 = 331.50 = semi-perimeter (s)
Now, to use Heron's formula:area = square root (s • (s - a) • (s - b) • (s - c))area = square root (331.5 • (331.5 - a) • (331.5 - b) • (331.5 - c))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (331.5 - 240) • (331.5 - 121) • (331.5 - 302))area = square root (331.5 • (91.50) • (210.5) • (29.5))area = square root ( 188,355,689.44 )area = 13,724.27

I don't know if you have heard of this question but if you
Answer:
(fog)(x) = 1/(x-2) + 3
Step-by-step explanation:
f(x) = 1/x² +3 g(x) = √(x-2)
(fog)(x) = f(g(x)) = f( √(x-2)) = 1/(√(x-2))² +3
(fog)(x) = 1/(x-2) + 3
