Using polygon STUVW what is m angle U ?

bija089 [108]

Answer:

The m∠ U is 72°.

Step-by-step explanation:

Given:

$\angle S = 90\\\angle T = 2x\\\angle U = x\\\angle V = 2x\\\angle W = 90\\$

To find :

$\angle U = x = ?$

Solution:

The sum of the measures of the interior angles of a polygon with 'n' sides is given as

$\textrm{sum of the measures of angle of a polygon with 'n' sides} = (n - 1)\times 180$

Here we have n = 5 on substituting the values we get

$\angle S +\angle T + \angle U +\angle V + \angle W = (5 -2)\times 180\\90 + 2x + x + 2x + 90 = 3\times 180\\5x + 180 = 540\\5x = 540-180\\5x = 360\\x = \frac{360}{5}\\x = 72$

Therefore,

m∠ U is 72°.

A one-sided hypothesis test for the proportion for a random sample of 50 the z-score of the

Sedaia [141]

Considering that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, it is found that it is significant at the 5% level, but not at the 1% level.

<h3>When a measure is significant?</h3>

If p-value > significance level, the measure is not significant.

If p-value < significance level, the measure is significant.

Using a z-distribution calculator, it is found that the p-value associated for a r<em>ight-tailed test with z = 2.115</em> is of 0.0172, hence, this is significant at the 5% level, but not at the 1% level.

Write an equation.

schepotkina [342]

Given:

y is proportional to x.

y=10 and x=8.

To find:

The constant of proportionality and the equation for the proportional relationship.

Solution:

y is proportional to x.

$y\propto x$

$y=kx$ ...(i)

Where, k is the constant of proportionality.

Putting y=10 and x=8, we get

$10=k(8)$

$\dfrac{10}{8}=k$

$\dfrac{5}{4}=k$

Putting $k=\dfrac{5}{4}$ in (i), we get

$y=\dfrac{5}{4}x$

Therefore, the contestant of proportionality is $k=\dfrac{5}{4}$ and the equation for the proportional relationship is $y=\dfrac{5}{4}x$ .
