AC ≈ 22.4mm

Step-by-step explanation:

Use the Pythagorean Theorem to find the missing length, where equals the missing length.

                     (Begin with the Pythagorean Theorem Formula)

              (Fill in your known variables)

         (Solve the exponents)

                      (Add the known variables together)

                (Undo the exponent on by using square-root)

22.4 ≈ c                            (You now have your rounded answer)

AC ≈ 22.4mm

I've attached a picture with a diagram to better show how to solve this equation.

I hope this helped :)

f(x) = y

f(-3) = -5

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°
