To measure the speed of a current, scientists place a paddle wheel in the stream and observe the rate at which it rotates. if the paddle wheel has radius 0.20m and rotates at 100rpm, find the speed of the current in m/s.

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
