Answer:
(A)A triangle with angles 45 degrees, 45 degrees, and 90 degrees. 2 sides are congruent.
Step-by-step explanation:
If Javier wants to construct a square by drawing two congruent triangles.
- One of the angle of the triangle must be equal to 90 degrees to form one of the vertex of the square.
- The other two sides of the triangle must be equal(congruent) to form the two adjacent side lengths of the square. This gives rise to an Isosceles Triangle with base angles of 45 degrees each.
Therefore, the triangle which could be used is a triangle with angles 45 degrees, 45 degrees, and 90 degrees.
The correct option is A.
It depends on the size of the circle to have an exact number but in general if you cut the circle in 4's equally then that would equal 1/4 or .25

Answer:
The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)
Step-by-step explanation:
The standard form of the equation of a parabola is (y - k)² = 4p (x - h), where
- The vertex of the parabola is (h , k)
- The focus is (h + p, k)
∵ The vertex of the parabola is (3 , -2)
∴ h = 3 and k = -2
∵ The focus is (5 , -2)
∴ h + p = 5
- Substitute h by 3 to find p
∵ 3 + p = 5
- Subtract 3 from both sides
∴ p = 2
∵ The standard form of the equation of the parabola is (y - k)² = 4p (x - h)
- Substitute the values of h , k , and p in the equation
∴ (y - -2)² = 4(2) (x - 3)
∴ (y + 2)² = 8 (x - 3)
The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)
