I'm sure you know the formula for Pythagoras Theorem.
The formula is 
C = Your hypotenuse
A + B = The other two adjacent sides.
So you plug in the numbers
And you'll get the answer, which is 56.
Well the first thing you have to do is find the sum of the numbers given. 5.2 + 8.3 + 8.5+ 7.7+ 7.8= 37.5
the equation would now be 37.5+y/6 = 7.1
After this you multiply 7.1 by 6 which is 42.6 turning the equation to 37.5 + y = 42.6.
Then you subtract 37.5 from 42.6 making y =5.1
No, 3,0 the x is to the right three and the y is zero. But 0,3 the x is zero and the y is up three
Answer:
100 resident/km
Step-by-step explanation:
In order to find the population density, we have to calculate the area of the township first.
We know that:
L = length = 5 km
W = width = 4 km
So the area of the township is
A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km
2
Now we can find the population density by using
d=\frac{N}{A}d=
A
N
where N is the number of residents, and A is the area.
Substituting N = 2000, we find:
d=\frac{2000}{20}=100 res./km^2d=
20
2000
=100res./km
2
so, 100 residents per kilometer squared
Angles are directly proportional to their corresponding side. So, 1 is <C, <A, <B. 2 is <A, <H, <T and for three all the angles combined =180. so, 180-55-95= 30 so Side A, Side C, then Side B
