What is the value of x in the triangle? - correct Answers3
First, drag a value to represent the missing angle in the triangle. Then, complete the
trigonometry equality statements. - correct Answersmissing angle = 90 - theta
sin 28 = cos 62
cos 33 = sin 57
cos 31 = sin 59
cosine 90 - theta = sin(theta)

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? - correct
Answers5.19 units
Circle O has radius of 24 units. Arc XY located on the circle has a central angle of 75∘.

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? - correct AnswersWhen 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? - correct AnswersDraw 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? - correct
Answers[X] AD
A quadrilateral is inscribed in circle O. The angle measures of the quadrilateral, in
