Solve to find x and y in the diagram.
Kipish [7]

Considering the given <em>information</em> in the question, the value of x is 12^{o}, and that of y is 7.5^{o}.

A <u>transversal</u> is a <em>line</em> that <em>cuts</em> through two given parallel lines. Thus it i<em>ntersects</em> each parallel line at a point, forming <u>four</u> angles each.

From the given <em>information</em> in the question, it can be <em>inferred</em> that:

the given<u> bottom</u> right angle of the first<em> intersection</em> and the bottom right angle with the <em>second intersection</em> are <u>congruent </u>(corresponding angle property).

So that,

(5x+4y)^{o} = (12y)^{o}

5x^{o} = 12y^{o} - 4y^{o}

5x^{o} = 8y^{o}............ 1

Also given that the top <em>right angle</em> at the<u> second</u> intersection is a <em>right </em>angle, then;

    12y^{o} + 90^{o} = 180^{o} (sum of angles on a straight line)

This implies that;

    12y^{o} = 180^{o} -    90^{o}

       12y^{o}  =     90^{o}

So that,

y = \frac{90}{12}

y = 7.5^{o}

Thus substituting the value of y in equation 1, we have;

5x^{o} = 8y^{o}........ 1

     = 8(7.5)

5x = 60

x = \frac{60}{5}

x = 12^{o}

Therefore, x = 12^{o} and y = 7.5^{o}

The price of a skateboard, which normally sells for $50,, was decreased by 10% then decreased again by 10%, then increased by 10
AveGali [126]

Answer:

The price dropped by $5.45.

Step-by-step explanation:

    Initial price = $50.00

      Less 10 % =   -5.00

 1st sale price =   45.00

       Less 10% =    -4.50

2nd sale price =   40.50

      Plus 10 % =   +4.05

     Final price = $44.55

Change in price =   final   -  initial

                          =   44.55 - 50.00

                          = -$5.45

The price dropped by $5.45.
