X = 18/sin47
x = 24.612
Bumek [7]2 years ago
5 0

Answer:

x ≈ 26.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos47° = \frac{adjacent}{hypotenuse} = \frac{CD}{AD} = \frac{18}{x} ( multiply both sides by x )

x × cos47° = 18 ( divide both sides by cos47° )

x = \frac{18}{cos47} ≈ 26.4 ( to the nearest tenth )

Which algebraic expression is a polynomial with a degree of 5?
Eddi Din [679]
The degree of a polynomial is the highest exponent or sum of exponents of the variables in the individual terms of a polynomial.

Looking at each the polynomial:

3x5 + 8x4y2 – 9x3y3 – 6y5: Degree is 6 (look at the 2nd and 3rd term)

2xy4 + 4x2y3 – 6x3y2 – 7x4: Degree is 5 (look at 1st, 2nd, and 3rd term)

8y6 + y5 – 5xy3 + 7x2y2 – x3y – 6x4: Degree is 6 (look at 1st term)

–6xy5 + 5x2y3 – x3y2 + 2x2y3 – 3xy5: Degree is 6 (look at 1st and last term)

Therefore, the answer is the second option:
2xy4 + 4x2y3 – 6x3y2 – 7x4
