One thing you should note is that the cross line and the line parallel to the shape of a triangle. We are told that the base is 4 and the angle between the hypotenuse and the shorter leg is 45°from this, we can solve for the second stage. Here is the list of trig functionssinФ = opposite/hypotenusecosФ = adjacent/hypotenusetanФ = opposite/adjacentSince only we are given the adjacent and we are trying to solve for the opposite leg, we can deduce we use tanФ. So getMultiply by 4 to isolate x and obtain = xHopes this helps!
