All the triangles are similar, so the ratio of (long leg)/(short leg) is the same. The long leg of ΔADB is
.. AD = AC -DC = 20 -4
.. AD = 16
Then
.. (long leg)/(short leg) = AD/DB = BD/DC
.. 16/h = h/4
.. h^2 = 64
.. h = 8
Selection D is appropriate.
_____
You may see this again. The altitude (h) from the right angle in a right triangle is the geometric mean of segments AD and DC. That is,
.. h = √((AD)*(DC))
Answer:
163%
Step-by-step explanation:
Find in-between 25 and 300, which is 162.5 ,round to the nearest percentage being 163%. Hence your answer
Answer:
66.42
Step-by-step explanation:
66.42 is already rounded to the nearest hundredth.
Answer:
points A, B and D are all in the same plane but not all are on the same line
Step-by-step explanation:
points A, C, D are all collinear which means they must also be coplanar
A line has the following standard equation form:
y = m x + b
where m is the slope and b is the y intercept
So if Ariel cannot find the slope, then this would only
mean that m = 0, there is no slope. And hence the line is either a straight
vertical line or straight horizontal line.
Answer:
<span>There is no slope</span>
