Solve triangles using the law of sines

BC = 18.7

Step-by-step explanation:

Here, we want to solve the triangle using the law of sines

According to the law, the ratio of the measure of the side of a triangle and the sine of the angle that faces the side is a constant for all sides of the triangle

Mathematically;

a/sin A = b/sin B = c/sin C

with reference to this particular triangle, we have it that;

20/sin 80 = BC/ sin 67

BC = 20 * sin 67/sin 80

BC = 18.7

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
