Answer:
Okay, so because angles A, B, and C make a triangle and a triangle is 180 degrees. So, because we know both A and B's measurement's, we can figure out the measurement of C. We can find the measurement of angle C by adding angles A and B and subtracting the total by 180 degrees.
Step-by-step explanation:
Answer:
b. angle I

Answer:
The answer is: 8a + 5b - 9
Answer:
Step-by-step explanation:
Let, 
= y
sin(y) = 
---------(1)
cos(y) = 
= 
= 
Therefore, from equation (1),
Or ![\frac{d}{dx}[\text{sin}^{-1}(\frac{x}{6})]=\frac{1}{6\sqrt{1-\frac{x^2}{36}}}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5B%5Ctext%7Bsin%7D%5E%7B-1%7D%28%5Cfrac%7Bx%7D%7B6%7D%29%5D%3D%5Cfrac%7B1%7D%7B6%5Csqrt%7B1-%5Cfrac%7Bx%5E2%7D%7B36%7D%7D%7D)
