Find the missing value. show your work. round to the nearest hundredth.

a. 9.33

b. 67.38°

Step-by-step explanation:

a) You can calculate the length  y as following:

Where:

Substitute values and solve for y:

b. You can calculate the missing angle as following:

Where:

When you substitute values  you obtain the following result:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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°
