Determine if the two triangles aré congruent? A) SAS
B) HL
C) AAS
D) Not enough information

A) SAS

The tickmarks tell us which pair of sides are congruent.

The sides with single tickmarks are the same length. The sides with double tickmarks are the same length.

The arcs drawn for the angles show they are the same measure.

The angle is between the two congruent sides for each triangle. The angle must always be between the two congruent sides to use SAS.

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

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
