Answer: A
Step-by-step explanation: You can use the pythagorean theorom to figure this one out. For all right traingles the sum of one of the smallest sides squared plus the sum of the other smallest side squared equal the biggest side squared or a^2+b^2=c^2. Which ever one of these doesnt fit the equation isnt a right traingle. 5^2+9^2=106, 11^2=121 106121.

Step-by-step explanation:
First question:
You are given a side, a, and its opposite angle, A. You are also given side b. Use that in the law of sines and solve for the other angle, B.
The sine function can never equal 2, so there is no triangle in this case.
Answer: no triangle
Second question:
You are given a side, b, and its opposite angle, B. You are also given side c. Use that in the law of sines and solve for the other angle, C.
One triangle exists for sure. Now we see if there is a second one.
Now we look at the supplement of angle C.
m<C = 52.5°
supplement of angle C: m<C' = 180° - 52.5° = 127.5°
We add the measures of angles B and the supplement of angle C:
m<B + m<C' = 63° + 127.5° = 190.5°
Since the sum of the measures of these two angles is already more than 180°, the supplement of angle C cannot be an angle of the triangle.
Answer: one triangle
