Answer:
Step-by-step explanation:
For this exercise you can use the following formula for calculate the slope:
In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:
Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:
Finally, evaluating, you get that the slope of this line is the following:
Answer:
m∠A ≈ 43°
m∠B ≈ 55°
mBC ≈ 20
Step-by-step explanation:
Law of Sines:
Step 1: Find m∠B
Step 2: Solve for ∠B
29sinB = 24sin82°
sinB = 24sin82°/29
B = sin⁻¹(24sin82°/29)
B = 55.038°
Step 3: Find m∠A
180 - (55.038 + 82)
180 - 137.038
m∠A = 42.962°
Step 4: Find BC
Step 5: Solve for BC
29sin42.962° = BCsin82°
BC = 29sin42.962°/sin82°
BC = 19.9581
