1. x = 60 degrees, y = 50 degrees
2. e = 85 degrees
3. f = 158 degrees
Answer:
1/4)(32 - 4 1/2) = (1/4)*27.5 = 6.875 min
The mean per quarter is 6.875 min.
Step-by-step explanation:
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:
6x + 2 and 3x + 1 are both equal to y, so they are both equal to each other.
6x + 2 = 3x + 1
3x = -1
x = -1/3
And plugging -1/3 in for x yields y = 0.
