53 would be your answer :) to figure this out, you would do 180-108 because a straight line is 180 degrees so you would subtract 108 to get 72. Next, you would add 72+55 and end up with 127. So you would do 180-127 to get the measure of angle 0. Hope this helped!
Answer:
x^2+y^2=81
Step-by-step explanation:
the equation is
(x-h)^2+(y-k)^2=r^2
since the center is (0,0) you don't even put it in the equation
so all you will have is the x and the y
you leave in the square (^2)
you divide the diameter by 2 to get the radius
9
then you square the radius
81
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places
I'm not smart, but I'm PRETTY sure it's the third one
First you want a common denominator: 15/12 - 9/12. Simplify: 6/12 which is 1/2.
