Answer:
c = 7.5 meters.
Step-by-step explanation:
hello :
use phtagore - rule :
c² = 6²+4.5²
c² = 36 + 20.25
c² =56.25
c = √56.25
c = 7.5 meters.
If you take the top number and divide it by the bottom number and you see the same number repeating over and over then that is a repeating decimal.
Example: 2/3 = 0.66666666666...
the 6 repeats so it is a repeating number.
43 and 57. Because 43 is 3 above 40 and 57 is 3 below 60.
First, divide 1 by 3 and 1 by 2.
1 divided by 3 = <span>0.33333333333
1 divided by 2 = 0.5
Add them up. </span>0.33333333333 + 0.5 = <span>0.83333333333.
Divide </span>0.83333333333 by 2, since there are 2 numbers we added up. 0.83333333333 / 2 = 0.41666666666, and <span>0.41666666666 as a fraction is 5/12.</span>
SinA=BC/AB =>BC=sin75*12
cosA=AC/AB =>AC=cos75*12
the area is (1/2)AC*AB=(1/2)sin75*12*cos75*12=18
