The length of the base of an isosceles triangle is 12 inches. Each base angle measures 50°. Which is a feasible plan to find the length of each congruent side of the triangle? Justify each step.
A) Draw the altitude from the vertex angle to the base of the triangle. Since the altitude is perpendicular to the base, 2 congruent right triangles are created. Then, use the sine ratio to find the length of each congruent side.
B) Draw the altitude from the vertex angle to the base of the triangle. Since the altitude is perpendicular to the base, 2 congruent right triangles are created. Then, use the cosine ratio to find the length of each congruent side.
C) Draw the altitude from the vertex angle to the base of the triangle. Since the altitude is perpendicular to the base, 2 congruent right triangles are created. Then, use the tangent ratio to find the length of each congruent side.
D) Draw the altitude from the vertex angle to the base of the triangle. Since the altitude is perpendicular to the base, 2 congruent right triangles are created. Then, use the Pythagorean Theorem to find the length of each congruent side.
