A^2 + b^2 = c^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289=289
It is a triangle because the numbers match the Pythagorean Theorem.
Well, both AMC are on the line I don’t exactly understand what the question is
Answer:
5.03%
Step-by-step explanation:

so it gives 5.03%
hope this helps
Step-by-step explanation:
quick ...
first we need to find x.
and then we can calculate the area by
baseline × height / 2
which is here
12 × x / 2
x we get via Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
15² = 12² + x²
x² = 15² - 12² = 225 - 144 = 81
x = 9
the area of the triangle is then
12 × 9 / 2 = 6×9 = 54 m²
