Answer:
<h2>49.5°</h2>
Step-by-step explanation:
Given the trigonometry function as shown sin W = 0.79, to get W, the following steps must be followed.
Step 1: Take the arcsin of both sides of the equation
![sin^{-1}(sinW) = sin^{-1}0.79\\W = sin^{-1}0.79](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%28sinW%29%20%3D%20%20sin%5E%7B-1%7D0.79%5C%5CW%20%3D%20sin%5E%7B-1%7D0.79)
Step 2: Use a calculator to get the resulting value of W
![W = 49.46^{0}](https://tex.z-dn.net/?f=W%20%3D%2049.46%5E%7B0%7D)
(to nearest tenth of a degree)
This gives the acute angle needed.
Note that acute angle are angles that are less than 90°

Answer:
The rectangular coordinates of the point are (3/2 , √3/2)
Step-by-step explanation:
* Lets study how to change from polar form to rectangular coordinates
- To convert from polar form (r , Ф) to rectangular coordinates (x , y)
use these rules
# x = r cos Ф
# y = r sin Ф
* Now lets solve the problem
∵ The point in the rectangular coordinates is (√3 , π/6)
∴ r = √3 and Ф = π/6
- Lets find the x-coordinates
∵ x = r cos Ф
∵ r = √3
∵ Ф = π/6
∴ x = √3 cos π/6
∵ cos π/6 = √3/2
∴ x = √3 (√3/2) = 3/2
* The x-coordinate of the point is 3/2
- Lets find the y-coordinates
∵ y = r sin Ф
∵ r = √3
∵ Ф = π/6
∴ y = √3 sin π/6
∵ sin π/6 = 1/2
∴ y = √3 (1/2) = √3/2
* The y-coordinate of the point is √3/2
∴ The rectangular coordinates of the point are (3/2 , √3/2)
First you add up all the items and the coupon then you will get $24.51. then subtract $50.00 take away $24.51 then you will get $25.49. So when she left the store she had $25.49
