<span>The cosine of pi/2 is 0 so the problem really says "find the angle between - pi/2 and pi/2 whose tan = 0. That would be the same as asking for the angle whose sin is 0. That would be 0.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:

The angle is 0°.

Step-by-step explanation:

Consider the provided trigonometric function.

tan^{-1}(cos\frac{\pi}{2})

The given interval [\frac{-\pi}{2}, \frac{\pi}{2}]

The value of cos\frac{\pi}{2}=0

Now substitute the respective value in the provided trigonometric function.

tan^{-1}(tan(0))=0 by inverse property of trigonometric function

Hence, the angle is 0°.

How many distinct triangles can be formed for which m∠A = 75°, a = 2, and b = 3?
antiseptic1488 [7]
We can use the Sine Law:a / sin A = b / sin B2 / sin 75° = 3 / sin B2 / 0.966 = 3 / sin B  ( after that we will cross multiply )
2 sin B = 3 · 0.9662 sin B = 2.898sin B = 2.898 : 2sin B = 1.499 > 1  ( it is not possible )Answer:  A ) No triangles can be formed.
