Answer:
x = 5
Step-by-step explanation:
You want to find x such that ...
x^2 +(x +1)^2 = 61
2x^2 +2x -60 = 0 . . . . . simplify, subtract 61
x^2 +x -30 = 0 . . . . . . . divide by 2
(x +6)(x -5) = 0 . . . . . . . . factor; solutions will make the factors be zero.
The relevant solution is x = 5.
Answer: Are
Explaning
I think they are similiar because there is parralel lines they are perpendicular and opposite angles are equal making 25 = its oppisite side
Yes. Use pythagorean theorem to find that: 9^2 + 12^2 =225 and 15^2 =225.
