The two triangles are similar all angles are equal.
the sides are proportional
10/22 = AQ/AQ + 18
22AQ = 10 AQ+ 180
12 AQ = 180
AQ = 15
1. A pentagonal pyramid has 6 faces, 10 edges, and 6 vertices
2. The polygons you would need to construct a pentagonal pyramid are a triangular or rectangular pyramid. Or probably just a triangle and a pentagon (I’m not sure, hope I helped)
-- 44% of the people surveyed preferred WWCN.
-- 22% of the people surveyed preferred WANR.
-- The difference is 22% of the people surveyed.
That's how many MORE of the people surveyed
preferred WWCN than WANR.
-- 22% of the people surveyed is 22% of 400 people = 88 people .
Strange as it may seem, "88" is not one of the choices.
Go figure !
And how come the breakdown of the answers to the survey
adds up to 103% ? Did 12 of the surveyed people have
more than one favorite ? ?
Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
Suppose
is even, i.e. there is some integer
such that
. Then
where
is just some other integer. Therefore
is odd, proving the contrapositive, and so the original statement is also true.
