In the picture provided, right triangle ABC is drawn with a 72 degree angle. For right triangles with it an angle of 72 degrees
the ratio of the side opposite the 72 degree angle compared to the hypotenuse is 19/20. If the hypotenuse. AC has a length of 100 what is the length of the opposite side to 72° angleBC.

Answer:
Step-by-step explanation:
Perimeter of the rhombus, STAR, is the sum of the length of all it's 4 sides.
The coordinates of its vertices are given as,
S(-1, 2)
T(2, 3)
A(3, 0)
R(0, -1)
Length of each side can be calculated using the distance formula given as
Find the length of each side ST, TA, AR, RS, using the above formula by plugging in the coordinate values (x, y) of each vertices.
S(-1, 2) => (x1, y1)
T(2, 3) => (x2, y2)
T(2, 3) => (x1, y1)
A(3, 0) => (x2, y2)
A(3, 0) => (x1, y1)
R(0, -1) => (x2, y2)
R(0, -1) => (x1, y1)
S(-1, 2) => (x2, y2)
Disregard the 9x+3y in the pic. The answer is 3/4x-13/12=y
