Answer:
B
Step-by-step explanation:
Given that ∠A ≅ ∠B, Evelia conjectured that ∠A and ∠B are acute angles.
Consider all options:
A. If m∠A=114° and m∠B=170°, then angles A and B are not congruent, so this is not a counterexample.
B. If m∠A=126° and m∠B=126°, then angles A and B are congruent and both these angles are obtuse (their measures are greater than 90°). This means that two obtuse angles can be congruent, so this is a counterexample. True option.
C. If m∠A=30° and m∠B=40°, then angles A and B are not congruent, so this is not a counterexample.
D. If m∠A=45° and m∠B=45°, then angles A and B are congruent, so this examples show two congruent acute angles. But if we have to prove some statement, we have to prove this statement for an arbitrary angles, not for one pair of angles. Moreover, this is an example illustrating given statement, but is not a counterexample.
A cube has six faces,8 vertices and 12 edges
There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Answer:
Find out the how much does each pair of socks cost when bought individually .
To prove
Let us assume that the original price of one pair of shoes be x.
Than cost for three pair of shoes be 3x.
As given
Maritza is buying a multipack of 3 pairs is socks for $25.98.
She will save $6.39 by buying multipack instead of buying 3 individual pairs of the same socks.
Than the equation becomes
3x - 25.98 = 6.39
3x = 25.98 + 6.39
3x = 32.37
x = $10.79
Therefore each pair of socks cost when bought individually is $10.79 .
The answer is 50 because 50 times 10 is equal to 500.
