we are given
equilateral triangle
we can see that triangle ACD is a right angled triangle
so, we can use Pythagoras theorem for this triangle
hypotenuse=AC
Adjacent=CD
opposite=AD=a
and
now, we can use Pythagoras theorem
and we get
now, we can plug values
now, we can solve for a
so, option-A..........Answer
Answer: 0.22kg
Step-by-step explanation:
if she has 3 kg then she has 3000 g. 3220-3000=220 So she needs 220 more grams of titanium. If she needs to convert how much more from grams to kilograms then 220g= 0.22kg so she needs 0.22 kg more
To check work
3kg+0.22kg= 3.22kg
3.22kg= 3,220g
