Unit 10 Practice 1 (H)

Jackie is looking at a map of a zoo. He notices that the bears and the tigers are 455 feet apart as shown. How far are the bears and the tigers each from the lions? Round to the nearest foot.

• b = 480 ft

• b = 495 ft

• t = 350 ft

• t = 336 ft

• t = 325 ft

Alex states that you cannot use the Law of Sines to find the unknown lengths of this triangle because you do not know the length of the side between the given angles. Is Alex correct? Explain your reasoning. If it is possible, find the missing measures of the triangle.

• Alex IS CORRECT,

  there is NOT ENOUGH INFORMATION

• Alex is NOT correct,

  there IS ENOUGH INFORMATION
