Answer:
C) Kite
Step-by-step explanation:
The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.
Therefore, the answer is C) Kite
Hope this helps!
The letter i in mathematics represents √-1. So, keep in mind. i = √-1.
Let's factor √-32 with the i in mind.
√-32 = √(32 * -1) = √32 * √-1 = √32i.
Just remember this formula: √-x = i√x
Answer: 20
Step-by-step explanation:
Formula to find the minimum sample size(n) when prior population standard deviation
is known.
, where E = Margin of error , 
= Critical z-value for c confidence interval.
Given : E = 225 g , 
g
Critical z value for 90% confidence = 1.645
Now, 
Hence, the required minimum sample size = 20
