Let the line segment BD be x, then sin A = x/15
or, x = 15sinA
Also

The last option
Well perimeter is lengthx2 and widthx2 so 7x2=14
then 64-14=50
50÷2= 25
length=25
The answer is C cause from
10
1m = 100cm.
so since the ladybug is 2cm.
you divide 2 by 100, which you will get 0.02m (divide by 100 means moving the dot two times to the left. thats why it leaves you 0.02m)
