B. <span>She is correct. The remaining angle of the triangle measures less than 90 degrees.</span>
Answer:
F
Step-by-step explanation:
Area of sector=pi*r^2*(theta/360) = pi*r^2*(45/360)
18*pi=pi*r^2*(1/8), r=12. Circumference is 24*pi
D. because PQR and XYZ are not congruent
Answer:
C
C=2πR
circumference equals two times pi times radius
Answer:
That is a infinite solutions equation, but to solve this you would have to subtract 3x from both sides and you will get 4=4.
Step-by-step explanation:
3x+4=3x+4
<u>-3x -3x</u>
4=4
