Question

1. Find all the missing parts for the triangle. (graph and keep one digit after decimal, calculator ok) A=26',c = 107°, b = 33. 2. How many triangle(s) can you make for each problem from the given information? Graph and show your work. Keep your answers in one decimal place caloulator ok. a) A-65°, a -18m b = 22. b)A-58°, a = 20, b = 22.

circle with radius a=18 С b A = 65° B с a will never meet point B, thus it will never have a solution
