Answer:

$\overset{\frown}{WX}= 66^{\circ}$

Step-by-step explanation:

<u>Inscribed Angle Theorem</u>

The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.

First, use the Inscribed Angle Theorem to calculate the measure of arc WY.

$\displaystyle \angle WXY=\dfrac{1}{2} \overset{\frown}{WY}$

$\implies 57^{\circ}=\dfrac{1}{2} \overset{\frown}{WY}$

$\implies \overset{\frown}{WY}= 2 \cdot 57^{\circ}$

$\implies \overset{\frown}{WY}= 114^{\circ}$

Assuming XY is the diameter of the circle:

$\implies \overset{\frown}{WY}+ \overset{\frown}{WX}= 180^{\circ}$

$\implies 114^{\circ} + \overset{\frown}{WX}= 180^{\circ}$

$\implies \overset{\frown}{WX}= 180^{\circ} - 114^{\circ}$

$\implies \overset{\frown}{WX}= 66^{\circ}$

I don’t understand this problem

GuDViN [60]

z^2 - z - 72

z^2 - 9z + 8z - 72

<u>Step 1</u>: 72 = 9 * 8 and when we subtract -9+8 = -1 and that's how I went from z^2 - z - 72 to z^2 - 9z + 8z - 72.

<u>Step 2</u>: Taking out common value from first and second; and third and fourth.

z^2 - 9z = z(z - 9)

8z - 72 = 8 (z - 9)

z^2 - 9x + 8x - 72

z(z-9) + 8(z-9)

(z-9) (z+8)
