What side lengths equal a right triangle? choose all that apply

Mathematics
1 answer:
Lerok [7]3 years ago
3 0

Answer:

A, B and C.

Step-by-step explanation:

If its a right triangle then c^2 = a^2 + b^2  where a, b and c are the 3 sides, c being the hypotenuse.

3^2 + 6^2 = 9 + 36 = 45

and (√45)^2 = 45   so the first set  (A) is a right triangle.

2.5^2  + 6^2 = 6.25 + 36 = 42.25.

6.5^2 = 42.25  so B is also a right triangle.

C:

4^2 + 8^2 = 16 + 64 = 80

(√80)^2 = 80 so C is  right-angled also.

Graph both functions to find the solution(s) to the system. Use the line tool to graph the line.
kumpel [21]
The graph shows solutions to be ...
  (x, f(x)) = (x, g(x)) = (-2, 5), (2, -3)

_____
Analytically, it works well to find
  g(x) -f(x) = 0
  (x^2 -2x -3) -(-2x +1) = 0
  x^2 -4 = 0
  x^2 = 4
  x = ±√4 = ±2
Then
  f(-2) = -2(-2) +1 = 5
  f(2) = -2(2) +1 = -3
