Lighthouse B is 8 miles west of lighthouse A. A boat leaves A and sails 6 miles. At this time, it is sighted from B. If the bearing of the boat from B is N63°E, how far from B is the boat?
The boat is either miles or miles from lighthouse B, to the nearest tenth of a mile.
(Use descending order. Do not round until the final answer. Then round to the nearest tenth as needed.)

answer: finding the extract measurements and knowing the points

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

none of these
