2. What is the circumference of a circle whose area is 100% ? [2 points) (A) 10
(B) 20
(C) 10x
(D) 20%
(E) 25x

you can not drow on this

step-by-step explanation:

14

step-by-step explanation:

14 x 3 = 42

you can't solve x because it is 2 linear equation and you only have one equation

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°
