In the diagram, . To prove that △VWZ ~ △YXZ by the SAS similarity theorem, which other sides or angles should be used? WV and XY
WV and ZY ∠VZW ≅ ∠YZX ∠VWZ ≅ ∠YXZ
2 answers:
Step-by-step explanation:
To prove that △VWZ ~ △YXZ by SAS theorem, we must prove that two of the sides for each triangle is congruent, and the angle inbetween the sides are congruent. Depending on which side is given to you, choose the one that conforming to it. For example:
Figure 1:
Side HJ is congruent with side ML, Angle J is congruent with angle M, Side IJ is congruent with side KM (SAS)

Answer:
No these these result do not differ at 95% confidence level
Step-by-step explanation:
From the question we are told that
The first concentrations is
The second concentrations is
The first sample size is
The second sample size is
The first standard deviation is
The first standard deviation is
The mean for Turnpike is
The mean for Tunnel is
The null hypothesis is
The alternative hypothesis is
Generally the test statistics is mathematically represented as
Generally the degree of freedom is mathematically represented as
The significance is evaluated as
=>
=>
The critical value is evaluated as
From the student t- distribution table
So
=>
given that
we fail to reject the null hypothesis so this mean that the result do not differ
