Answer:
11.3 Km
Step-by-step explanation:
Consider the right triangle formed by AB and West.
The acute angle WAB = 270° - 250° = 20°
and West is the adjacent side of the right triangle with AB the hypotenuse
Using the cosine ratio in the right triangle, then
cos20° = =
Multiply both sides by 12
12 × cos20° = adjacent
11.2763.. = adjacent, that is
B is 11.3 Km west of A
The angle B will be equal to ∠B=53.13 degrees.
<h3>What is the triangle?</h3>Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
It is given that:-
Three sides of the triangle are:- a= 3, b=4 and c =5
The angle B will be calculated by the following formula;-
∠B=53.13 degrees
Hence the angle B will be equal to ∠B=53.13 degrees.
