Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:
You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial that the highest exponent is "2", which is the exponent of the term 
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.
Answer:
The length of the ladder is 14.5 ft
Step-by-step explanation:
For a right triangle
sinx = opposite / hypotenuse
Since we know the angle and the opposite side, we can calculate the hypotenuse
sin 64 = 13/ hypotenuse
Multiply each side by the hypotenuse
hypotenuse * sin 64 = 13
Divide by sin 64
hypotenuse = 13/sin 64
hypotenuse=14.4638
Rounding to the nearest tenth
14.5
Because Angle A and B are supplementary they will ad up to 180 degrees.
the measure of angle A is 101 degrees
