Answer:

The two odd numbers are 15 and 17

Step-by-step explanation:

Given

<em>Let the odd numbers be represented with x and y</em>

<em>Let x be the greater number</em>

<em></em> $x + 5y = 92$ <em></em>

<em></em>

<em>Required</em>

Find x and y

Since x and y are consecutive odd numbers and x is greater, then

$x = y + 2$

Substitute y + 2 for x in $x + 5y = 92$ <em></em>

<em></em> $y + 2 + 5y = 92$ <em></em>

<em></em>

Collect Like Terms

<em></em> $y + 5y = 92 - 2$ <em></em>

<em></em> $6y = 90$ <em></em>

Divide both sides by 6

$\frac{6y}{6} = \frac{90}{6}$

$y = \frac{90}{6}$

$y = 15$

Substitute 15 for y in $x = y + 2$

$x = 15 + 2$

$x = 17$

<em>Hence; the two odd numbers are 15 and 17</em>

What is the measure of arc WZY?

Radda [10]

Answer:

<h2>m arc WZY = 222°</h2>

Step-by-step explanation:

Look at the picture.

m∠WOY = 2(m∠WZY)

We have m∠WZY = 69°. Therefore m∠WOY = 2(69°) = 138°.

m arc WZY = 360° - 138° = 222°
