Question

In right ∆ABC, m B = 90°, m C = 40°, and BC = 10. What are the other two side lengths of the triangle?

Answer 1

AC = 13.1, AB = 8.4



AC = 18.7, AB = 15.8



AC = 14.3, AB = 10.2



AC = 15.6, AB = 11.9

Answer 2

im confused

Answer 3

\[\frac{ AC }{ \sin90 }=\frac{ BC }{ \sin50 }\]
BC=10

Answer 4

can you calculate AC?

Answer 5

its 1

Answer 6

how?
AC=\[\frac{ 10 }{ \sin50 }*\sin90\]
use a calculator

Answer 7

Not understanding this either.
