Answer:
A=52.8 miles (approximately)
Step-by-step explanation:
We can assume that this triangle is not a right angle, therefore we cannot use Pythagorean theorem. Let's use the Law of Sines:

Where A is unknown, a=28 miles, b=32 miles, B=87°
Therefore by law of sines we have:

By multiplying 28 to Isolate sin(A) we have:

To cancel out sine on the right, we must multiply both by the inverse sine and so:

Answer:
Step-by-step explanation:
Hint:
a² - 9a + 15 = (a-7)(a-2)
a² + 9a + 15 = (a+7)(a+2)
a² + 3a - 10 = (a-2)(a+5)
a² + 5a - 14 = (a-2)(a+7)
a² - 5a - 14 = (a-7)(a+2)
You need to change 15% to a decimal and multiply it by 25
25 x 0.15 = 3.75
Then add 3.75 to 25 to get the total
25 + 3.75 = 28.75
So, the answer is 28.75$
