Answer:
x=50
Step-by-step explanation
The two angles add up to 180, so 2x+4+76 = 180
2x+80=180
2x=100
x=50
First, let's calculate the area of the rectangle. Find the distances between the length and the width. For the width we can use point A and point D.
(2, 2) and (20, 2)
20 - 2 = 18
So the width is 18 cm. Now find the length. We can use point A and point B.
(2, 2) and 2, 26)
26 - 2 = 24
So the length is 24.
So the area of the rectangle is 432 square centimeters, now let's find the area of the circle.
The radius is given as 15 cm. Use 3.14 to approximate for pi.
So the area of the circle is approximately 706.5 square centimeters. Subtract this area from the area of the rectangle to find the value of the shaded area.
Insert y and you get
X=0
Then insert x and you get
Y=-5
Answer:
Option A
2:1
Step-by-step explanation:
The radius of circle B is half of that of A meaning circle A's circumference is twice that of B
Answer:
yes it would be 1
