One side of an obtuse triangle is 17 cm smaller than the other. find the sides of this triangle

One side of an obtuse triangle is 17 cm smaller than the other. find the sides of this triangle if its perimeter is 77 cm

Let’s take the side of the rectangle as x, then:
x + 17 – side.
The perimeter of a rectangle is determined by the formula: P = 2 * (a + b) P- perimeter, a and b sides. Then we get the equation:
2 * (x + x + 17) = 77
2 * x + 17 = 77/2
2 * x = 77 / 2-34 / 2 = 43/2
x = 43/4 cm.
The other side is equal to: 43/4 + 34/4 = 77/4 cm.
