Consider a triangle ABC for which ZA= 105°, a = 28, b = 18. If such a triangle can not exist, then write NONE in each answer box. If there could be more than one such triangle, then enter dimensions for the one with the smallest value for side c. Finally, if there is a unique triangle ABC, then enter its dimensions. LB is degrees; degrees; LC is C =

State if the three side lengths form an acute, obtuse, or right triangle show work & the formula is c=a+b .

For the three-part question that follows, provide your answer to each part in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C. View the rubric linked above if needed. Part A: In complete sentences, explain what information must be known about an oblique triangle in order to use the law of cosines to find unknown side lengths and/or angle measures. For Part B and Part C, use ABC below. A 20 m b 120° B Note: The figure is not drawn to scale. 23 m Part B: Solve the triangle. Show all work and round to the nearest tenth. Part C: In complete sentences, explain how the law of sines could have been used to solve the triangle.
