Identify the transformation that carries the figure onto itself. a) reflect across the line x = −5 and rotate 180° clockwise about (−3, −8) b) reflect across the line y = −5 and rotate 180° clockwise about (−3, −8) c) reflect across the line x = −3 and rotate 630° clockwise about (−3, −8) d) reflect across the line y = −3 and rotate 630° clockwise about (−3, −8)

X+ y = 5 ; x - y =3 solve using linear combination

Andy wants to find the distance d across a river. he located points as shown in the figure, then use similar triangles to find that d = 223.5 feet. how can you tell without calculating that he must be wrong? tell what you think he did wrong and correct his error. round your answer to the nearest tenth if necessary. andy must have used the wrong . the distance d is actually feet.
