To calculate the other angles, we need the sine, cosine and tangent. In fact, the sine, cosine and tangent of an acute angle can be defined by the ratio between sides in a right triangle. Just like every other triangle, a right triangle has three sides. One of them is the hypothenu...
The ladder's length is thehypotenuseof the triangle, and the ground distance is theadjacentside to the angle. So long as the triangle has one right (90 degree) angle, the information you have determines the formula you need to use. Cosine: Calculate the cosine angle if you know the lengt...
Calculate the cosine by dividing the adjacent leg by the hypotenuse. Using the previous triangle, you would divide 5 by 13, for a cosine of 0.384. Step 3 On your calculator, input the value of either your sine or your cosine. Then press "inv." This should give you the angle associated...
