You don't have to give me an answer to the question, I just need an explanation on how to work these problems.

147

explanation: a straight line is 180° so 180-33= 147

Explanation:

When a transversal cuts 2 parallel lines, there are only 2 answers for each of the 8 angles formed. 33 is one of them. x is the other. x and 33 are supplementary

x + 33 = 180               Subtract 33 from both sides

x +33 - 33 = 180 - 33

x - 147

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
