Answer:
Step-by-step explanation:
this is exactly the same as the 1st one, just they put it in a different orientation. sooo use law of cosines , where
QR = c
a = 12
b = 23
cos(120) = cos (P)
c = sq rt [ a^2+b^2﹣2*a*b*cos(P) ]
QR = sq rt [ 12^2 + 23^2 - 2* 12*23*cos(120) ]
QR = sq rt [ 144 + 529 - 552 * (-0.5 0 ]
QR = sq rt [ 673 + 276 ]
QR = sq rt [ 949 ]
QR = 30.8058
rounded to nearest 10th is
QR = 30.8 :)
Answer:
d) 54 ft = 1645.92 cm
Step-by-step explanation:
Given : 54 ft.
To find : Approximately how many centimeters are in 54 ft.
Solution : We have given 54 ft.
We know
1 ft = 30.48 cm .
54 ft = 54 * 30.48 cm.
54 ft = 1645.92 cm.
Therefore, d) 54 ft = 1645.92 cm.
1 plus 1 equals 2 ,2 times 0 equals 0 .get it.
The answer is true because the X (to the right) values does not repeat itself
