An isosceles triangle has two congruent sides of length 9 inches. The remaining side has a length of 6 inches. Find the angle that a side of 9 inches makes with the 6-inch side. (Round your answer to two decimal places.)
◻ radians
Begin by drawing a reference triangle with side lengths corresponding to the lengths given in the problem. Which angle is being asked for in the given triangle? How can an isosceles triangle be drawn as two triangles so that right triangle trigonometry can be used?
