Applying the law of sines, the measurement indicated are:

7. AB = 24.1 cm

8. BC = 28.0 in.

<h3>What is the Law of Sines?</h3>

Law of sines is: sin A/a = sin B/b = sin C/c.

7. AB (c) = ?

BC (a) = 22 cm

A = 180 - 138 - 22 = 20°

C = 22°

Apply the law of sines:

sin 22/AB = sin 20/22

AB = (sin 22 × 22)/sin 20

AB = 24.1 cm

8. BC (a) = ?

A = 58°

AC (b) = 33 in.

B = 180 - 58 - 33 = 89°

Apply the law of sines:

sin 58/BC = sin 89/33

BC = (sin 58 × 33)/sin 89

BC = 28.0 in.

Which ordered pair is a solution to the inequality?<br><br> Help please!!
Murrr4er [49]

Choice A is the answer which is the point (1,-1)

=========================================

How I got this answer:

Plug each point into the inequality. If you get a true statement after simplifying, then that point is in the solution set and therefore a solution. Otherwise, it's not a solution.

-------------

checking choice A

plug in (x,y) = (1,-1)

y - 2x \le -3

-1 - 2(1) \le -3

-3 \le -3

This is true because -3 is equal to itself. So this is the answer.

-------------

checking choice B

plug in (x,y) = (2,4)

y - 2x \le -3

4 - 2(2) \le -3

0 \le -3

This is false because 0 is not to the left of -3, nor is 0 equal to -3. We can cross this off the list.

-------------

checking choice C

plug in (x,y) = (-2,3)

y - 2x \le -3

3 - 2(-2) \le -3

7 \le -3

This is false because 7 is not to the left of -3, nor is 7 equal to -3. We can cross this off the list.

-------------

checking choice D

plug in (x,y) = (3,4)

y - 2x \le -3

4 - 2(3) \le -3

-2 \le -3

This is false because -2 is not to the left of -3, nor is -2 equal to -3. We can cross this off the list.
