Need fast! a scientist is trying to measure the distance across a marsh as shown in the figure above. he chooses two points at either end of the marsh representing the endpoints of the desired distance, d. he then chooses another point away from the marsh's border so that a right triangle is formed. he calculates that the angle between the base of this triangle and its hypotenuse is 45° . he then measures one of the sides of the triangle to be 300 m. what is the length, d, across the marsh? round to the nearest tenth of a mete

That is a 45 45 90 triangle.The hypotenuse of such a triangle equals one of the legs multiplied by the square root of 2.300 * sq root (2)=300 * 1.4142135624 Distance "D" = 300 * 1.4142135624 Distance "D" = 424.3 meters
(rounded to the nearest 10th of a meter.
