Rounded to the nearest tenth, what is the perimeter of the triangle? (30,60,90 hypotenuse =
5cm) - answer✔11.8 centimeters
What is the value of x in the triangle? - answer✔3
First, drag a value to represent the missing angle in the triangle. Then, complete the
trigonometry equality statements. - answer✔missing angle = 90 - theta
sin 28 = cos 62
cos 33 = sin 57
cos 31 = sin 59
cosine 90 - theta = sin(theta)
On a football field, the left and right tackles are lined up on the same yard line. A linebacker is
15 yards away from that yard line. The angles of the lines of sight of the tackles to the
linebacker that are made with the yard line are shown in the diagram. Approximately how far
apart are the left and right tackles? - answer✔39.3 yards
An airplane departs airport A at a heading of 300∘ (N 60∘W). After traveling 320 miles, the
airplane adjusts its course to 350∘ (N 10∘W) and flies an additional 112 miles to reach airport B.
- answer✔401 miles

transitive property of equality
In the diagram, point M is the center of the circle. If m∠PMN = 134°, what is m∠PON? -
answer✔67
In the given figure, what is the measure of angle CPE? - answer✔[X] 68
The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle
is 81°. What is the approximate length of the radius of the circle? - answer✔5.19 units
Circle O has radius of 24 units. Arc XY located on the circle has a central angle of 75∘. What is
the area of the associated sector, in square units? - answer✔120pi
Jenna attempted to construct equilateral triangle EFG inscribed in circle C.
First, she used a compass to draw circle C and labeled its center. Next, she used a straightedge
to draw a diameter of the circle. She labeled the endpoints of the diameter D and E. Then,
keeping the compass set equal to the radius of circle C, she drew an arc centered at point E,
which intersected the circle at two points that she labeled F and G. Finally, she used a
straightedge to draw three chords connecting points E, F, and G.
What was the first error Jenna made in her construction? - answer✔When Jenna drew the arc
that intersected circle C, she should have used point D as the center of the arc.
In her notebook, Pia wrote these steps to construct a square inscribed in a circle:
Use a compass and a straightedge to find chord LM, which is the perpendicular bisector of JK.
Then, use a straightedge to draw the four chords that make up the square: JL, LK, KM, and MJ.
Which instruction is Pia missing? - answer✔Draw any diameter on a circle and label it JK.
In ABC, the angle bisectors meet at point D. Point E is on , and is perpendicular to . Point F is the
location where the perpendicular bisectors of the sides of the triangle meet. What is the radius
of the largest circle that can fit inside ABC? - answer✔[X] AD
A quadrilateral is inscribed in circle O. The angle measures of the quadrilateral, in degrees, are
given by the expressions shown in the figure. - answer✔[X] 75
A circle is defined by the equation given below.
�2 + �2 − � − 2� − 114 = 0
What are the coordinates for the center of the circle and the length of the radius? -
answer✔(/2, 1) 2 units
Which equation represents circle N? - answer✔(x + 7)2 + (y − 6)2 = 50
