Formula = (a + b)^2 = a^2 + 2ab + b^2
x^2 + 4x + 4 + 9 = 0
x^2 + 4x + 13 = 0
Answer:
A kite.
Step-by-step explanation:
A quadrilateral with 2 pairs of adjacent sides that are congruent is called a kite.
In Euclidean geometry, when a quadrilateral has two (2) pairs of adjacent sides congruent and no opposite sides congruent it referred to as a kite.
Answer:
The angle between them = 52.1°
Step-by-step explanation:
∵ The position vector of the first point is
∵ The position vector of the second point is
∵ The magnitude of the first = √(1²+5²) = √26
∵ The magnitude of the second = √(6²+3²) = √45
∵ The scalar product of them = (1 × 6) + (5 × 3) = 6 + 15 = 21
∵ cosФ = scalar product/(magnitude 1st × magnitude 2nd)
∴ cosФ = 21/(√26 × √45) = 0.61394
∴ Ф = 52.1°
