The  vertices are   ( 7, -7)   ( 9,- 7) ( 9, -9) and ( 7, -9)

The point farthest from the origin can be found as

[ old point - dilation center] (scale factor) + dilation center  =

[ (9, -9) - (0,0) ] (2)  + (0, 0)  =

[ 9, - 9 ] (2)  + (0, 0)  =

(18 , - 18) + (0, 0)     =

(18, - 18 )

sin 75 = shadow length / 150

150 * sin 75  = 144.9 ft

cos R  =   adjacent side / hypotenuse

Can you find the answer based on this, NSS ???

Well....what side IS opposite angle F ???

Note that

P2 * V2  =  k   =  8.59 * 527  =    4526.93  

So

P1 * V1  =  k

5.42 * V1  =  4526.93          divide both sides by 5.42

V1  =  4526.93 / 5.42  =  835 ml

cos 20  =  adjacent / hypotenuse

Using this, NSS.....can you find the solution???

Evaluate

65 * 4.5

y = k / x

y = 6 / 12

y = 1/2

tan R  =   opposite side / adjacent side

Can you find this, NSS   ???

The side opposite the right angle is the hypotenuse.....

The other two sides are the legs

Can you find the answer, NSS ???
