Answer:
r=-45
Step-by-step explanation:
<u>r/5=-9</u>
OUR GOAL: To isolate the variable "r" on one side...
1) Multiply both sides of the equation by 5 to get r on one side:
r=-9*5
2) Multiply:
r=-45

Answer: approximately 6.3 miles</h3>
=================================================
Explanation:
See the diagram below. The two given angles B = 105 and C = 20 are used to help find angle A
A+B+C = 180
A+105+20 = 180
A+125 = 180
A = 180-125
A = 55
Then we use the law of sines to find the side length c
sin(A)/a = sin(C)/c
sin(55)/15 = sin(20)/c
c*sin(55) = 15*sin(20) ... cross multiply
c = 15*sin(20)/sin(55) .... divided both sides by sin(55)
c = 6.26294249724791 .... value is approximate
c = 6.3 ....... rounding to one decimal place
