Answer:
72 square units
Step-by-step explanation:
The area is given by the formula ...
A = 1/2ab·sin(C)
A = 1/2(12)(24)sin(30°) = 1/2(12)(24)(1/2) = 72 . . . square units
For this, since 4y - 7 and 2y - 1 are congruent, we can solve for y by setting them equal to each other.
Firstly, subtract 2y on both sides of the equation.
Next, add 7 on both sides of the equation.
Finally, divide 2 on both sides of the equation, and your answer will be y = 3
