It is given that in △abc, ad ⊥ bc. using the definition of sine with angle c in △acd results in sin(c) = . using the multiplication property of equality to isolate h, the equation becomes bsin(c) = h. knowing that the formula for the area of a triangle is a = bh is and using the side lengths as shown in the diagram, which expression represents the area of △abc? bsin(c) absin(c) cbsin(c) hbsin(c)

We see here in the diagram that the base is a. We know this because the height is perpendicular to it. We also know the height is bsin(C) which, when replace h for bsin(C) and a for the base, we get A=absin(C), which is the second option.

Step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
