Answer:
z=63°{vertically opposite angle}
now,
z+10x+97=18o°{straight angle}
63+10x+97=180°
10x=180-133
x=<u>2</u><u>0</u>
<u> </u><u> </u><u> </u><u> </u><u> </u>10
x=2
hope it helps.

1. Area of a circle is pi(R)^2 , where R is the radius. So we can substitute:
22/7(16^2) = about 805 meters squared.
2. Let's find the area of the rectangle first.
A=LW
A= 18(10)
A= 180 cm squared.
Now the semi-Circle:
The radius of the circle is 9 (because 18/2 is 9). Now we plug in to the area formula:
22/7(9^2) = about 254 cm squared. But because that is the area of the whole circle, and we only need half of the circle, we divide that value by 2 to get:
127 cm squared for the semi-circle.
Now we add up the rectangle and semi-circle's areas:
180 + 127 = 307 cm squared as your answer.
I hope this Helps!
