Answer:

Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r =  .
.
In the equation you'd write that as r =  which can be simplified to
 which can be simplified to  .
.
You end up with  and you simplify this by doing
 and you simplify this by doing  , ending with the result of
, ending with the result of  .
.

8 and 32.
8 times 4 = 32
32 - 8 = 24
4x - x = 24.
