C = diameter * pi
19 * pi = 59.69 m^2, or 59.7
Hope I helped! (Pick my answer as brainliest!)
Answer:
When we draw the angle in what is known as standard position, we put its vertex at the origin, and we draw the initial side of the angle along the positive horizontal axis. ... The amount of that rotation corresponds to the measure of the angle.
Step-by-step explanation:
Simplify the following:
(sqrt(5) + 1) (sqrt(5) - 1) + 5 sqrt(5)
(sqrt(5) + 1) (sqrt(5) - 1) = -1 + 1 sqrt(5) - sqrt(5) + sqrt(5) sqrt(5) = -1 + sqrt(5) - sqrt(5) + 5 = 4:
Answer: 4 + 5 sqrt(5) or decimal 15.18033988749894848204586834365638117720309179805762862135
Here,
The midpoint of segment QR is M
<u>m</u><u>(</u><u>-2</u><u>,</u><u>9</u><u>)</u> x3=-2,y3=9
<u>Q</u><u>=</u><u>(</u><u>-8</u><u>,</u><u>1</u><u>2</u><u>)</u>x1=-8,y1=12
R=x2,y2
we know that,
⠀
So,
x3= ⠀
⠀
⠀
⠀
⠀
x2=4
now we find the y coordinate y2.
y3= ⠀
⠀
⠀
⠀
⠀
y2=6
<em>Now</em><em> </em><em>we</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>R</em>
<em>so</em><em>,</em>
R=(x2,y2)=(4,6)
5 minutes will be reamaning but . the two people get 18 minutes so to get equel time for 5 minutes one person gets 2:30 and other 2;30 more
