Answer:
(a) 63.125 in²
Explanation:
You want the area of a triangle with sides 12 in and 24 in and angle 26° between them.
Area
The area is given by the formula ...
A = 1/2ab·sin(C)
Using the given values, that is ...
A = 1/2(12 in)(24 in)·sin(26°) ≈ 63.125 in²
The area of ∆ABC is about 63.125 in², choice A.
