Find the number of distinct triangles with measurements of A=31 a = 10, and b = 40
i think doesn t exsist:
\(\frac{10}{\sin{31}}=\frac{40}{sinB} \\ 10sin(B)=40\sin(31) \\ sin(B)=2.06015229964\\ B=?\)
but probably i am wrong so wait for boss
You are correct, Solveit
Using the Law of Cosines.....we can find the possible angle opposite the longest side
cos-1 [ (40^2 - 31^2 - 10^2) / (-2*31*10) ] =
cos-1 [ -0.8693548387096774] = about 150.38°
But.....this angle, added to the given one of 31°, would give us a triangle wose angle sum > 180......which is impossible.....
