The harbormaster wants to place buoys where the river bottom is 20 feet below the surface of the water. Complete the absolute value equation to find the horizontal distance from the left shore at which the

buoys should be placed.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
