Answer:
O Sin (53) = 21/29
O Sin (37) = 20/29
Step-by-step explanation:
In a triangle, the sine is opposite over hypotenuse, the cosine is adjacent over hypotenuse, and the tangent is opposite over adjacent.
<h2>Steps:</h2>
Here are the steps to convert an equation to its inverse:
- Change f(x) to y
- Switch the positions of x and y
- Solve for y
- Change y to f^-1(x)
Firstly, do the first two steps:
Next, let's solve for y. Subtract 3 on both sides:
Next, divide both sides by 4:
Finally, change y to f^-1(x) and your final answer will be:
, or <u>the second option.</u>
First you have to find the angle B (check attachment)
Then you can find the last angle inside the triangle, which I'll call C
Now you can find angle A
