Answer:

B) 70.92

Step-by-step explanation:

a = 12

b = 15

C = 52°

[tex] area = \dfrac{ab \sin C}{2} [/tex]

[tex]area = \dfrac{12(15) \sin 52^\circ}{2}[/tex]

[tex] area = 70.92 [/tex]

Step-by-step explanation:

because 15 x 12 is 180 so multiply by .5 and you get 90 and 88.80 is the closest thing to 90
