A) What side or angle information can be identified as congruent besides ∠QPR≅∠SPR? B) What additional information is needed to prove these two triangles are congruent by AAS?

C) What additional information is needed to prove these two triangles are congruent by SAS?

D) What additional information is needed to prove these two triangles are congruent by ASA?

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
