Answer:

1/2c-4

Step-by-step explanation:

First, you distribute the fraction on the outside to the numbers inside of the parenthesis. So, you distribute 1/2 to c, which gives you 1/2 x c = 1/2c. Then, you distribute the 1/2 to -8, which gives you 1/2 x -8 = -4. You combine these expression together and get your final answer as 1/2c-4.

Svetach [21]

Answer:

16.26

Step-by-step explanation:

To find the angle of C, use the inverse sine function.

$Sin^{-1}(sin c) = Sin^{-1} \frac{7}{25}\\\\c = Sin^{-1} \frac{7}{25}\\\\c = 16.26$

Type into your calculator 7/25 = 0.28. Then type the $sin^{-1}$ key to find 16.26 degrees.
