45. In ?ABC below, ?A measures 101 , ?B measures 25 , and the length of BC is 165 meters. To the nearest meter, what is the length of AC ? (Note: The law of sines states that the lengths of the sides of a triangle are proportional to the sines of the opposite angles. Note also that sin 101 ? 0.982 and sin 25 ? 0.423.)

Step 1
So, we can find the measure of angle C by subtracting the measures of angles A and B from 180. Angle C = 180 - 101 - 25 = 54 degrees Show more…
