Answer: 76.56sqcm
Step-by-step explanation:
Area of rectangle= length * width
= 16 * 4 = 64sqcm
Area of semicircle= (1/2)(r^2)π
r= d/2= 4/2= 2
Area of semicircle= (1/2)(2^2)(3.14)
= 6.28sqcm
Area of bookmark= Area of rectangle + 2*Area of semicircle
Area of bookmark= 64 + 2(6.28)
=64 + 12.56 = 76.56sqcm
Answer:
Both equal 121 degrees
Step-by-step explanation:
Vertical angles are equal, and and 2 are indeed vertical angles. They are the "top" and "bottom" of the x formed. So you can use this.
angle 1 = angle 2
20x + 21 = 30x - 29
50 = 10x
5 = x
So just plug this in.
20x + 21
20(5) + 21
121
30x - 29
30(5) - 29
121
So both are 121.
