Answer:

(b) 33

Step-by-step explanation:

The side opposite x° and the hypotenuse are given. That means the relevant trig relation is ...

Sin = Opposite/Hypotenuse

sin(x°) = 6/11

The value of the angle is found using the inverse sine function:

x° = arcsin(6/11) ≈ 33.056°

x ≈ 33

_____

<em>Additional comment</em>

If you recall, the side length ratios of the "special" 30°-60°-90° triangle are 1:√3:2. Here, you have a shortest:longest side ratio that is 6:11 ≈ 6:12 = 1:2. This means the angle will be only slightly greater than 30°.

In which quadrant is the solution to this system of equations? 2x + 5y = 1<br> 3x - 4y = 13

Reptile [31]

Answer: Quadrant IV

Step-by-step explanation: Pic attached.

I found the x and y using substitution (isolating one variable and plugging it into the other). There was probably an easier way but I couldn't think of it at that moment.

From there, you have the point ( 133/36 , -23/18), or a (+, -).

Find Which quadrant has positive x and negative y.

In this case, this would be Quadrant IV or 4.

Hope this helps! Sorry if too complicated lol.
