8. at 60 deg north , on the shortest day of the year, you see the sun above the s horizon. [a] 0 degrees (never rises) [b] 6.5 degrees [c] 23.5 degrees [d] 30 degrees [e] 53.5 degrees

[C] 23.5 degrees

Explanation:

At the 60 degrees of the north, the shortest day of the year the sun is seen at the s horizon of about at an angle of 23.5 degrees at this place lies in the arctic circle and has a tilt farther away from the sun as seen on December solstice. This is due to the sun rays have to pass through as rarefied atmosphere that is thin and denser as compared to the clean and clear air at the tropics. Hence a place located in this altitude will experience slanting sun rays and will have high-pressure air mass from above.

It's lithogenous i believe of course i looked it up.

343^x = 49^4-xx = 4-xx+x=42x = 4x = 4/2x = 2therefore x = 2
