For each problem below, complete the given table of values. Then sketch a graph that shows two complete cycles. 1. y=-cos x(Hint: Find the value of cosine, then take its opposite)
2. y=sin x+1 (Hint: Fond the value of sine, then add 1)

For each proportion find the unknown number x 1/5/8=×/15

In triangle △abc, ∠abc=90°, bh is an altitude. find the missing lengths. ah=4 and hc=1, find bh.

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
