Answer: 65
Step-by-step explanation:
All those angles added up have to equal 360 degrees.
The little square on the angle to the left of x means that it's a right angle, or 90 degrees.
360
- 180
= 180 <--- this is the bottom half,
180
- 90 <--- the right angle on the left
= 90
90
-25
= 65 <--- that's x
subtract them
593.7-573.36 = 20.34seconds
so c is the answer
Do you think it could be 'rho' (density)? Like the thing you use for calculating pressure in fluids?
...or maybe it's just a fancy P.
