Two sides are 3x longer than the shortest side. So, set up your problem like this.
X = unknown length in centimeters
3X = length of two longer sides
1X = length of short side
3x + 3x + 1x = 49
7x = 49
x = 7
So, two longer sides are 21 centimeters each and the short side is 7 centimeters.
21+21+7 = 49


where
is the Jacobian matrix for the transformation,

We have

so that the integral is

Step-by-step explanation:
Answer:
x = 2 , y = 11
Step-by-step explanation:
the diagonals of a parallelogram bisect each other , then
PT = TR , that is
y = 5x + 1 → (1)
QT = TS , that is
2y = 6x + 10 → (2)
substitute y = 5x + 1 into (2)
2(5x + 1) = 6x + 10
10x + 2 = 6x + 10 ( subtract 6x from both sides )
4x + 2 = 10 ( subtract 2 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
substitute x = 2 into either of the 2 equations for corresponding value of y
substituting into (1)
y = 5(2) + 1 = 10 + 1 = 11
We are given an angle of elevation of 2 degrees and distance in the x axis of 5280 feet and we are asked in the problem to determine the height of the building. We use the tangent function to determine the height: that is tan 2 = h / 5280; h is equal then to 184 ft.
