stellarik [79]

C is correct,

A is wrong as it halves both the angles and lengths by two which is the same as what she did in the first place so it cannot be correct.

B is also wrong for a similar reason, a triangle cannot have less than 180 degrees, which is impossible as the angles just change naturally which is why all triangles must have 180 degrees, which is the reason she is wrong in the first place.

And D is just incorrect, if she wanted to have shorter sides she should have only decreased all the lengths as it the the ratio of angles that determine the shape of a triangle while the sum of all angles is 180 degrees.

If sin Θ = 2 over 3 and tan Θ < 0 , what is the value of cos Θ?
Zielflug [23.3K]

\sin \theta = \dfrac 2 3

\tan \theta < 0

Positive sine, negative tangent, means we have a negative cosine.  We're talking about the second quadrant.

\cos^2 \theta + \sin ^2 \theta = 1

\cos^2 \theta = 1 - \sin ^2\theta

\cos \theta = \pm \sqrt{1 - \sin ^2\theta}

We know it's negative,

\cos \theta = - \sqrt{1 - (2/3)^2} =-\sqrt{5/9} = - \dfrac 1 3 \sqrt{5}

Answer: -(1/3)√5
