Divers looking for a sunken ship have defined the search area as a triangle with adjacent sides of length 2.75 miles and 1.32 miles. The angle between the sides of the triangle is 35 degrees. To the nearest 100th, find the search area.

If two adjacent sides of a triangle are A and B, and the angle between them is Ø, then the area of the triangle
= (1/2)AB sinØ
= (1/2)(2.75)(1.32)sin 35°
= ..
you can do the arithmetic.
btw, the units on your answers should be square miles, or mi^2 , not miles.
