Findtheareaofatriangle - Example 4

In mathematics, the area of a triangle is half the base times the height. It is a generalization of the concept of area in Euclidean geometry, where the base and height are the sides of the triangle and where the area is the length of any side times the area of the triangle.

angle using trigonometry functions. And in this triangle, the angle of the triangle that were given is B, which is 32 degrees and were given to other sides where a is 11 miles and see it's five miles. So since we're using trigonometry functions, we're gonna use the formula area is gonna equal half. Well, the two sides were given, so in this case it would be a Tom C. Tom Sant sign of the angle were given, which is 32 degrees. So we go one half of 11 Tom's fave and then sign of 32 degrees. So we're looking at one half of 55 Tom Sana, 32 half of 55 is 27.5 and we're gonna multiply that times sign of 32 which is zero point Bob three. And when I multiply that, I'm gonna get an area oven approximate value of 14 0.6 miles squared
