7.2 is the answer i hope this helps!
Given that:
A = 63
B = 56
C = 61 (since these angles should be equal to 180)
a =
b =
c = 1/2
sin 63 / a = sin 61 / .5
a = .51 miles
sin 56 / b = sin 61 / .5
b = .47 miles
The correct answers are: 0.51 miles and 0.47 miles. These are <span>the distances from each observer to the sailboat.

Answer: 22.5 inches
Step-by-step explanation:
- the general formula for finding perimeter is
- a pentagon contains 5 sides
- note that this is a regular pentagon so it must contain 5 congruent sides
- each side will be 4.5 inches
- the formula can be changed to
and solved:
∴ 22.5 inches = perimeter of the pentagon
