ZA and B are supplementary angles.
yKpoI14uk [10]

Answer:

135°

Step-by-step explanation:

a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.

180 - 45 = 135, therefore the measure of ZB = 135°.

If polynomial p(x) is divided by x + 4, the quotient is x^2-7x+34-144/x+4. Which of the following must be true?
Ber [7]

Answer:

B. P(-4)=-144

Step-by-step explanation:

From the question, we have that:

\frac{p(x)}{x + 4}  =  {x}^{2}  - 7x + 34 -  \frac{144}{x + 4}

This implies that:

p(x)=(x + 4)(  {x}^{2}  - 7x + 34) - 144

To find p(-4), we put x=-4

p( - 4)=( - 4+ 4)(  {( - 4)}^{2}  - 7 \times  - 4 + 34) - 144

p( - 4)=( 0)(  {( - 4)}^{2}  - 7 \times  - 4 + 34) - 144 =  - 144

To find p(0), we put x=0 to get:

p( 0)=( 0+ 4)(  {( 0)}^{2}  - 7 \times  0+ 34) - 144

p( 0)=(4)( 34) - 144 =  - 8

The correct answer is B
