Essentially, you would take the formula for the laws of sines and cosines: a^2=b^2+c^2-2bc(Cos(theta)). a is the unknown side you are solving for and theta is the opposite angle to a. Since the angle opposite to R is supplementary to the 50 degree angle, 180-50=130. b could be assigned to either of the given sides; the same goes for c (e.g. b=40 and c=38). Thus, the question should be straightforward in plugging in quantities and solving for the resultant force.

7nadin3 [17]

The answer is: 70 .
___________________________________________
Explanation:
_________________________________

(20/100) x = 14; solve for "x".

(20/100) = 2/10 = 1/5 ;

(1/5) x = 14

x/5 = 14 ;

x = 14 * 5 ;

x = 70 . The answer is: 70 .

Answer:

Segment addition postulate

Step-by-step explanation:

According to the segment addition postulate, given a line segment defined as AC then a point B is located along AC if and only if the length of the segments on the line satisfy the relation, AC = AB + BC. Therefore, whereby a line which is defined by two end points, is seen to be the sum of points between the two end points.
