Answer:
X=-22
Step-by-step explanation:
Answer:
- Prime: 3
- GCF: 1
- Factoring Trinomials: 4
- Difference of Squares: 2
- Perfect Square Trinomial (PST): 5
Step-by-step explanation:
1. Each term has an even coefficient, so a factor of 2 can be removed:
2(3x^2 +7x -15)
The remaining quadratic factor is prime.
__
2. Each of these two terms is a square, so this is the difference of two squares.
__
3. This cubic has one irrational negative real root. It is prime.
__
4. This trinomial factors in the usual way: (x +15)(x -2). It is factored by "factoring trinomials."
__
5. The magnitude of the x-coefficient is double the square root of the (positive) constant, so this is a perfect square trinomial.
Therefore, the measures of the angles in triangle ABC is as follows:
- m∠A 73.7°, m∠B = 16.3°, m∠C = 90°
<h3>How to find angles of right triangle?</h3>
The measure of the angles in the right triangle can be found as follows:
Using trigonometric ratios,
sin ∅ = opposite / hypotenuse
sin ∅ = 7 / 25
∅ = sin ⁻¹ 0.28
∅ = 16.2602047083
∅ = 16.3°
Hence,
m∠B = 16.3°
m∠C = 90°
m∠A = 180 - 90 - 16.3 = 73.7°

Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
