Need now which materials allow heat to pass through them easily?

The materials which allow heat to pass through them easily are conductors of heat. For examples,aluminum, iron, and copper.

Hope this helps! ;)

28.07 degrees

Step-by-step explanation:

To figure out these questions, you need to know inverse sin. To solve this question you do inverse sin (8/17) to get 28.07 degrees. You need to apply sin because it is opposite (8) over hypotenuse (17). Then, you need to make it inverse because you are figuring out the angle measure.
