Answer:

A0 2/5

Step-by-step explanation:

First, find out how many girls there are by subtracting 8 (boys) from 20 (total). This means there are 12 girls. Since 8 girls aren't speaking, 4 are. 4+4=8. 8 out of the 20 children are speaking/ 8/20 simplified is 2/5

Can anybody help me on this<br> 16<br> 16π<br> 16π - 16<br> 16 - 16π<br> are the answer choices

kvasek [131]

The answer is 16 pi - 16. The area of each triangle is 8, so both triangles are 16. The area of the circle is pi times the radius squared, 16 pi.

What is 80+x=200<br><br> also, meet my friend group

dedylja [7]

$\huge\text{Hey there!}$

$\huge\textsf{80 + x = 200}$

$\huge\textsf{x + 80 = 200}$

$\huge\text{SUBTRACT 80 to BOTH SIDES}$

$\huge\textsf{x + 80 - 80 = 200 - 80}$

$\huge\text{CANCEL out: 80 - 80 because that gives you 1}$

$\huge\text{KEEP: 200 - 80 because that helps for x}$

$\huge\textsf{x = 200 - 80}$

$\huge\textsf{200 - 80 = x}$

$\huge\textsf{x = 120}$

$\boxed{\boxed{\huge\textsf{Therefore, your answer x = \bf 120}}}\huge\checkmark$

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:

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

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

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

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