Answer:
h=13
P=5
b=12
Step-by-step explanation:
- tanA=<em>p</em><em>÷</em><em>b</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>2</em>
- sin<em>A</em><em>=</em><em>p</em><em>÷</em><em>h</em><em>=</em><em>5</em><em>÷</em><em>1</em><em>3</em>
- <em>c</em><em>o</em><em>s</em><em>A</em><em>=</em><em>b</em><em>÷</em><em>h</em><em>=</em><em>1</em><em>2</em><em>÷</em><em>1</em><em>3</em>
Answer: Line DB
Think of the two planes as pages in a book. They are joined by the spine, which is where the two planes intersect. In this case, that intersection is the line DB.
Point D is on both planes R and S. So is point B. Every point on line DB is found on both planes.

Answer:
<h2>Ceramic does not foster bacterial growth</h2>
Step-by-step explanation:
A good way to think and reason deeply about this is, most if not all toilet bowls are made of ceramics, this is so because ceramics when it dries out kills all hanging bacterial on its surface, hence does not easily permit the growth of bacteria on its surface.
Another wonderful application of ceramic is in the application of water treatment process, specifically in the use as a water filter to kill bacterial, hence it is evident that ceramic does not permit the growth of bacteria
