x = 6.

We know that the right angle is 90°. So:

(x + 54)° + 5x° = 90°

x° + 54° + 5x° = 90°

6x° + 54° = 90°

6x° = 90° - 54°

x = (90° - 54°)/6°

x = 36°/6°

x = 6

Then, solving for x we obtain:

5x° = 5(6)° = 30°

(x + 54)° = (6 + 54)° = 60°

1.Which expressions are polynomials? Select each correct answer. Pick more then one.
madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

1.

7x^{7}-x-5

35x^{2}

\frac{x}{5}+2

are polynomials.

2.

x^{2} -x\sqrt{2}

y

2 + s

4x^{2} +y

are all polynomials.

3.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, -5x^{3}-4x+1 is a cubic trinomial.

4.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
