O A. zero O B. one O C. two or more (b) A triangle with sides of length 3 cm and 5 cm and a nonincluded angle of 60° How many noncongruent triangles of this form can be drawn? O A. one O B. two or more O C. zero (c) An isosceles triangle with two sides of length 8 cm and an apex angle of measure 28° How many noncongruent triangles of this form can be drawn? O A. zero O B. one OC. two or more

A laser beam with an angle of elevation of 47° is reflected by a target and is received 1000 yards from the point of origin. Assume that the trajectory of the beam forms​ (approximately) an isosceles triangle. a. Find the total distance the beam travels. b. What is the height of the​ target?a. The total distance is ______ yards. (Do not round until the final answer. Then round to the nearest yard as​ needed.)b. The height of the target is _____ yards. (Do not round until the final answer. Then round to the nearest yard as​ needed.)
