If sin t = -8/17 and t is a quadrant III angle, find cot t

Mathematics

nirvana33 [79]3 years ago
8 0

Answer:cot t = 1.875

sin t=\frac{-8}{17} but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t

⇔cos t = \sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2}  }=|\frac{15}{17}|

but  t is a quadrant III angle => cos t = \frac{-15}{17}

=> cot t = \frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875

What is x? Options: 81, 57, 143, 66.
jeyben [28]

Answer:

x = 103

Step-by-step explanation:

In my opinion, because x and 77 are the supplementary angles, so 180-77 = x or x+77=180. The answer should be 103......even though it's not in the options (I'm sorry).

A circle has so many important properties.

The important of these are called theorems related to circles.

Some of the theorems are

i)Central angle theorem

ii) Opposite angles are supplementary for a cyclic quadrilateral, etc

Hence theorems would be the appropriate word for filling up the answer
