10^2+8^2-7^2/(2*10*8)
= 115/160 = 0.71875 round off to 0.72
I think you mean 'additives' and 'sum'
It's 8269 after you add it all together.
Answer:
The answer in the procedure
Step-by-step explanation:
we have the right triangle ABC
The pre-image coordinates are

The transformation to use is the translation
The rule of the translation is

That means----> The translation is 10 units to the right
The image coordinates are
Applying the rule of the translation


using a graphing tool
see the attached figure
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
