The answer for this question is very tricky but is to work out its B.
The resultant force would be 88.88 N at an angle of 43 degrees from the 100 N force.
Let
x,y, and z the long sides of the triangle
we know that
x+y+z=170 ft------> equation 1
x/y=25/14----> y=14x/25------> equation 2
y/z=14/12-----> equation 3
x/z=25/12----> z=12x/25------> equation 4
substitute equation 2 and equation 4 in equation 1
x+[14x/25]+[12x/25]=170------> multiply by 25 both sides
25x+14x+12x=4250
51x=4250
x=4250/51
x=250/3
y=14x/25------> y=(250/3)*(14/25)----> y=140/3
z=12y/14-----> (140/3)*12/14----> z=40
Using Heron's formula,
Area of the triangle = √s (s-a) (s-b) (s-c)
where s is the semiperimeter
s=170/2-----> s=85 ft
Area=√85*[85-250/3]*[85-140/3]*[85-40]
Area=9.22*[1.67]*[38.33]*[45]------> Area=26558.21 ft²
the answer is
26558.21 ft²
Answer:
Radians
Step-by-step explanation:
If you use degrees, you have to put an annoying 2π/360 every time you try to simplify. This is why in calculus, we work with radians for all functions of derivatives, since its much easier to work with, and you dont have to write that annoying constant.
-8/10,-12/15,-16/20,-20/25,-24/30,etc.
