Which equation finds the value of x in the triangle below? right triangle x y z is shown. Side x z has a length of 12, side z y has a length of x, and hypotenuse x y has a length of z. The angle opposite to side x is 20 degrees. Cotangent 70 degrees = startfraction x over 12 endfraction cotangent 70 degrees = startfraction 12 over x endfraction secant 20 degrees = startfraction x over 12 endfraction secant 20 degrees = startfraction 12 over x endfraction.
