Here the answer is 19/35
Step-by-step explanation:
![\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B5%7D%20X%5Cfrac%7B-2%7D%7B7%7D%20%2B%5Cfrac%7B4%7D%7B5%7D-%5Cfrac%7B3%7D%7B10%7D%20X%5Cfrac%7B2%7D%7B7%7D)
We will apply BODMAS rule
In this rule multiplication comes before add and subtraction
= ![\frac{-6}{35} + \frac{4}{5} - \frac{3}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B-6%7D%7B35%7D%20%2B%20%5Cfrac%7B4%7D%7B5%7D%20-%20%5Cfrac%7B3%7D%7B35%7D)
= ![\frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20-%20%28%20%5Cfrac%7B6%7D%7B35%7D%2B%20%5Cfrac%7B3%7D%7B35%7D%29)
= ![\frac{4}{5} - \frac{9}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20-%20%20%5Cfrac%7B9%7D%7B35%7D)
= ![\frac{4 X 7}{5 X 7} -\frac{9}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B4%20X%207%7D%7B5%20X%207%7D%20-%5Cfrac%7B9%7D%7B35%7D)
= ![\frac{28}{35} - \frac{9}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B35%7D%20-%20%5Cfrac%7B9%7D%7B35%7D)
= ![\frac{19}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B35%7D)
23,.88 plus the the next power
Considering that the sine is negative and that the cosine is positive, the angle is on the fourth quadrant, hence option C is correct.
<h3>What are the signs of the sine and of the cosine in each quadrant?</h3>
- Quadrant 1: Both positive.
- Quadrant 2: Sine positive, cosine negative.
- Quadrant 3: Both negative.
- Quadrant 4: Sine negative, cosine positive.
Hence, since the sine is negative and that the cosine is positive, the angle is on the fourth quadrant, hence option C is correct.
