Answer:
<h2>PT</h2>
Step-by-step explanation:
<em>A chord of a circle is a straight line segment whose endpoints both lie on a circular arc.</em>
The line PQ and QS are radiuses since they are a point from the center to the arc.
The lines PR is considered a diameter since it starts from an arc, runs through the center and ends at another arc.
Answer:
sin(angle) = opposite/hypotenuse
Sin(39) = 9/ hypotenuse
hypotenuse = 9/sin(39) = 14.3011
x = 14.30
Step-by-step explanation:
Answer:
YZ = 18
Step-by-step explanation:
XY = YZ because the line indicates they are the same length
XY = 18 so YZ = 18
Answer:
Because it is a rectangle, the area is expressed as A = xy, or length times width.
Because it is next to the river, he only needs to fence three sides, so F = x + 2y.
Knowing the amount of fencing available is 7500m, we get:
7500 = x + 2y solve for x
x = 7500 - 2y substitute into the area equation
A = (7500 - 2y)y distribute
A = -2y2 +7500y
You can see that this is a parabola which opens down, meaning that the point of maximum area will be at the vertex, y = -b/2a = -7500/[2(-2)] = 1875
x = 7500 - 2(1875) = 3750
A = 3750(1875) = 7,031,250 m2
