Question

Please! check my answer
Determine the number of possible solution for each triangle
A=113° ,a=15
b=8
a>b one solution ?

Answer 1

best way to understand this is not to use a formula. draw a reasonable triangle. that is, one where 113 looks close to 113. then see if you can figure out how to make two triangles, or if only one is possible

Answer 2

see label the sides and see if you think you can make two triangles with those conditions. it should be pretty clear that you cannot

Answer 3

if angle A was acute, then maybe you would have a chance, depending on a and b
