Process:
A. sin 18° = 0.31, and cos 72° = 0.31
A. works!
B. sin 55° = 0.82, and cos 55° = 0.57
B. does not work!
C. sin 72° = 0.95, and cos 18° = 0.95
C. works!
Hope this helps!

Conventional sources of energy is also called non-renewable sources of energy while non conventional sources of energy is called renewable sources of energy.
An example of conventional energy is coal, crude oil and natural gas. The advantage is the availability and affordability. The disadvantage is the level of air pollutants such as CO2 and CO it releases to the atmosphere which is harmful as it poses a risk of air borne illnesses.
An example of non conventional energy is the sun, wind , water etc. The advantage is that it reduces the risk of air pollution and keeps the environment clean as no toxic substances are being released into the atmosphere when used. The disadvantage is they are expensive and aren’t available all year round.
