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

@pooja195
hartnn (hartnn):
can you draw the triangle with the details?
that will help us easily identify which trigonometric to use...

Find the remaining angle A.
You can find the side AC using the sines law:
\(\displaystyle \frac{{\rm AC}}{{\rm Sin}(\angle {\rm~ B})}= \frac{{\rm BC}}{{\rm Sin}(\angle~{\rm A})}\)
THEN you can find AB either using sines law or pathegoryan theorem (a²+b²=c²)

((this is one possible set of steps to find the other 2 sides... you can do it different ways.))
