In AABC, if m ZA = 25° and mZB = 108°, what is mZC?
GrogVix [38]

Answer:

Step-by-step explanation:

Sum of all the angles of a triangle = 180°

∠A +  ∠B + ∠C = 180

25 + 108 + ∠C = 180

        133 + ∠C = 180

                 ∠C = 180 - 133

                ∠C = 47°

What is the value of  sinθ, given that cosθ=−2/5 and  sinθ>0? Simplify radicals and rationalize the denominator, if necessary
Vadim26 [7]
\cos\theta=-\dfrac25
\sin\theta=\pm\sqrt{1-\cos^2\theta}=\pm\dfrac{\sqrt{21}}5

Take the positive root, since it's given that \sin\theta>0.

\sin\theta=\dfrac{\sqrt{21}}5
