Use Angle of Elevation and Depression to set up a triangle, create an equation, and solve. Round to the nearest tenth. x=

care to share were the trapezoid shown is ?

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
