Simple geometry problem
vova2212 [387]

Answer:

Step-by-step explanation:

I gather that you need to find the area of the sector and then subtract from it the area of the segment to get the area of the triangle (although there are other ways in which to find the area of the triangle).

The area of a sector is:

A=\frac{\theta}{360}\pi r^2 where our angle is given as 34, pi is 3.1415, and the radius is 5:

A=\frac{34}{360}(3.1415)(25) and if you multiply and divide that all out you get that the area of the sector is:

A = 7.417

Now subtract from it the area of the segment, 2.209. to get the area of the triangle:

7.417 - 2.209 = 5.208
