the hypotenuse of a right triangle has a length of 13cm the longer of the two legs is 7cm longer than the shorter leg

1 answer:

6 0

Let's say the shorter side is x.

So, the longer side would be ( 7 + x )

Now we have to use the Pythagorean Theorem to find the value of x.

a² + b² = c²

( 7 + x )² + x² = 13

7² + x² + x² = 13²

49 + 2x² = 169

2x² = 169 - 49

2x² = 120

x² = 60

x = √60

So the longer side is ( 7 + √60 ) and the shorter side is √60

Answer:

Critical Value

Step-by-step explanation:

The critical value separates the region of rejection from the region of non rejection.

We define critical values as:

Critical value helps us to give the decision rule for the rejection or acceptance of null hypothesis.
Critical value separates the acceptance region from the rejection region.
These are referred to as cut-off values that define regions where the test statistic is unlikely to lie.
The critical value depends on the kind of test being performed and the significance level.
