To find the distance from the house at A to the house at B, a surveyor measures the angle ACB, which is found to be 70°, and then walks off the distance to each house, 50 feet(A to C) and 70 feet(C to B), respectively. How far apart are the houses? (answer to 1 decimal place) in feet

Best ResponseYou've already chosen the best response.0google gives me: sqrt((50^2) + (70^2)  (2 * 50 * 70 * cos(70))) = 54.4680234
