1 answer:
Amanda [17]3 years ago
5 0

Answer:

∠ A ≈ 75.7°

Step-by-step explanation:

Given

\frac{sinA}{8} = \frac{sin58}{7} ( cross- multiply )

7 × sinA = 8 × sin58° ( divide both sides by 7 )

sinA = \frac{8sin58}{7} , then

∠ A = sin^{-1} (\frac{8sin58}{7} ) ≈ 75.7° ( to the nearest tenth )

How to graph 3 ordered pairs
Vesnalui [34]

Answer: I'm assuming you just need to graph each ordered pair without doing anything else to them. The first number in the ordered pair is called the x-intercept, the second number is the y-intercept. To graph an ordered pair you need to count the x-intercept number and go to that number on the x-axis (horizontal), do the same for the y-intercept on the y-axis (vertical) and make a point/dot. Repeat this for the other two ordered pairs.
