5 0

Answer:

Step-by-step explanation:

45x = 9*5*x

81 = 9*9

GCF = 9

Take 9 out using distributive property { a*b - c*b = b*(a-b)}

45x - 81 = 9*5x - 9*9

= 9*(5x - 9)

=9(5x-9)

I) Construct a triangle PQR such that |PQ|=8cm,{RPQ=90°{PQR=30°.Measure |RQ|

scoray [572]

Answer:

6.93 cm

Step-by-step explanation:

You have a right triangle (90°), so you do as follow:

If I understand correctly, you are looking for the hypotenuse so

$cos(30) = \frac{PQ}{QR} = \frac{8 cm}{QR}$

That is equal to $QR = cos(30)*8 cm = 6.928 cm$
