Answer:
you have to be specific, i don´t understand the question
please rewrite the question
Assuming the choices are A,B,C,D in that order from left to right (according to your attachments), then it would be the fourth one.
To make sure we're on the same page, I'm attaching your fourth drawing below. It's the result of taking a triangle and reflecting it over the horizontal x axis. Think of it like mirroring an image.
Answer:
- (x + 2.4)² + (y + 4.8)² = 45
Step-by-step explanation:
<u>Circle equation:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center, r - radius
<u>Substitute the values to get the equation:</u>
- (x - (- 2.4))² + (y - (-4.8))² = (√45)²
- (x + 2.4)² + (y + 4.8)² = 45
Answer:
Right triangles:
5) 0.75, 1, 1.25
6) 18, 80,82
Not right triangles:
1) 5,5,√50
2) 6.5, 3.2, 7.8
3) √2, √3, 4
4) 12, 13, 20
Step-by-step explanation:
Right triangles: (for right triangles the Pythagorean theorem is true)
6) 18² + 80² = 82²
6724=6724
5) 0.75² + 1² = 1.25²
1.5625 =1.5625
Not right triangles:
1) 5² + 5² ≠(√50)²
1250≠ 50
2) 6.5² + 3.2² ≠ 7.8²
52.49≠60.84
3) (√2)² +(√3)² ≠ 4²
5≠ 16
4) 12² + 13² ≠ 20²
313 ≠ 400
