Find the measure of the angle between two forces of 30 pounds and 35 pounds if the magnitude of their resultant is 42 pounds

100 degrees

Step-by-step explanation:

30^2+35^2-2*30*35cos80

=42

180-80=100

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
