Calculate the area of a piece of property bounded by a traverse and circular arc with the following coordinates (in meters) at angle points: A (1479.838,1803.583), B (1204.998, 1813.173), C (1204.728, 1447.473), D (1654.728, 1447.473) and a circular arc of radius CD starting at D and ending at A with the curve outside the course AD.

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
