Mark only stated equalities, right angles and parallel lines. Select the relationship that connects the given dimensions to the requested angle, length or area.
Two angles of a triangle measure 37 and 58 degrees. How many degrees is the exterior angle at the third vertex?
Answer:
A regular polygon has exterior angles of 24 degrees. How many sides does it have?
Answer:
A right triangle has legs 9 and 12. What is the radius of the circle with its hypotenuse as diameter?
Answer:
A circle of radius 6 has a sector with central angle 120 degrees. What is the sector's area divided by pi?
Answer:
A chord is 16 units long in a circle of radius 10. What is the perpendicular distance from the center to the chord?
Answer:
A tangent from point P touches a circle at T. The center O satisfies OP=13 and OT=5. What is PT?
Answer:
Two sides of a triangle have lengths 4 and 9. How many positive integer lengths are possible for the third side?
Answer:
A square is inscribed in a circle of radius 5. What is the square's area?
Answer:
A circle's circumference is 18 pi. What is its area divided by pi?
Answer:
Two concentric circles bound a ring. Their radii differ by 3 and their circumferences sum to 30 pi. What is the ring's area divided by pi?
Answer:
Check whether a squared scale factor is needed, and distinguish a radius from a diameter before interpreting the final measure.
