That depends on what x is: a leg, an angle, what?
That will depend on other values of the triangle because a triangle has 3 sides and 3 interior angles that add up to 180 degrees
You get the sine of the angle. For a right triangle: sin (x) = opposite/hypotenuse cos (x) = adj./hypotenuse tan (x) = opposite/adj
find the lenght of the hypotenuse of a right triangle whose sides are (3x-1)cm and (x+2)cmImproved answer by David Gambell:-0.5*(3x-1)*5x = 6015x2-5x-120 = 0Solving the quadratic equation gives x a positive value of 3Using Pythagoras: 82+152 = 289 and its square root is 17So the hypotenuse is 17 cm
Well that totally depends on the polygon, if it's a hexagon, triangle, square, the answers are different
