You can use the tangent function to find the adjacent leg.
tan 15= 40/adj = 40/tan 15 = 149.3 meters. This is the adjacent leg.
================================================================
We can also use the law of sines to find the adjacent leg.
40/sin 15 = x/sin 75. x = 149.3 meters.
================================================================
Next, we can use a^2 + b^2 = c^2 to find the hypotenuse.
1600 + 22290.49 = 23890
sqrt%2823890%29= approx 154.5 meters
===================================================================
We can also use the law of sines to find the hypotenuse.
40/sin 15 = x/sin 90 x = approx. 154.5 meters
