will give medal to best answer!
The given measurements may or may not determine a triangle. If not, then state that no triangle is formed. If a triangle is formed, then use the Law of Sines to solve the triangle, if it is possible, or state that the Law of Sines cannot be used.
C = 38°, a = 19, c = 10

Best ResponseYou've already chosen the best response.0i got sin A = 67 but that isnt in my answer choices No triangle is formed. A = 58.6°, B = 83.4°, b ≈ 15.6 A = 83.4°, B = 58.6°, b ≈ 15.6 The triangle cannot be solved with the Law of Sines.

Best ResponseYou've already chosen the best response.3I don't understand how you got that. Please show me the steps you took to get A = 67

Best ResponseYou've already chosen the best response.0i used c/ sin c = a/ sin a 10/sin 37 = 19/sin a and then i divided 19 sin 38 over sin 10 and i got 67.36

Best ResponseYou've already chosen the best response.3where did you get the 37 from?

Best ResponseYou've already chosen the best response.0I meant 38, i used 38 in my claculations and still got 67

Best ResponseYou've already chosen the best response.0i dont know i just typed it in and got 67, cant you check it?

Best ResponseYou've already chosen the best response.3You must make sure you're in degree mode. That's very important.

Best ResponseYou've already chosen the best response.3But either way it goes, you're not doing it correctly.

Best ResponseYou've already chosen the best response.0oh really, i hadnt noticed that im doing it wrong. I need help thats why im on here obviously

Best ResponseYou've already chosen the best response.3Compute the right hand side again and let me know what you get. Make sure you're in degree mode.

Best ResponseYou've already chosen the best response.3Okay now \[\sin A = 1.169756803\] So how do we find A?

Best ResponseYou've already chosen the best response.0a is 19, sin A is 1.16, what do you mean find A?

Best ResponseYou've already chosen the best response.3I'm not talking about a = 19. That's a side length

Best ResponseYou've already chosen the best response.3\[\sin (A^{\circ}) = 1.169756803\] I'm talking about Angle A. Find that.

Hero

Best ResponseYou've already chosen the best response.3You take the inverse sine of both sides to get: \[\sin^{1}(A^{\circ}) = \sin^{1}({1.169756803}) \\A^{\circ} = \sin^{1}({1.169756803}) \]

Hero

Best ResponseYou've already chosen the best response.3So compute \[\sin^{1}({1.169756803})\]

Hero

Best ResponseYou've already chosen the best response.3That's what it should say because no such angle exists.

Hero

Best ResponseYou've already chosen the best response.3And if the angle doesn't exist, then the triangle can't possibly exist.

Best ResponseYou've already chosen the best response.3\[1< \sin(\theta) < 1\] means that the value of sine can only be between  or + one. So there's no such thing as \(\sin(\theta) = 1.17\)
