Which is the best estimate for (2.8 times 10 Superscript 3 Baseline) (4.1 times 10 Superscript 6 Baseline) written in scientific notation?

7 times 10 Superscript 9

1.2 times 10 Superscript 10

1.5 times 10 Superscript 10

12 times 10 Superscript 18

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°

the answer is:

mean: 6

mad: 2.14
