Answer:
38.46
Step-by-step explanation:
Answer:
14.29cm
Step-by-step explanation:
Height of the building=10cm
Angle of depression=60°
We are therefore asked to find the distance from the stone to the
the foot of the building;Therefore we use Tan ratio which is opp/adj;
Let the distance from the stone to the foot of the building be x;
10/x=Tan60°
10/x=1.7/1
We then cross multiply to get 1.7x=10
x=10/1.7
=10*10/1.7*10
=100/17
=14.29cm.
<span>- - Star to simplify both sides of the equation.
</span>
<span>- - Now you have top subtract 18 from both sides.
</span>
- - Solve:
<span>- - And divide both sides by -4.
- - Solve:

For every decimal place that you move over, add one to the exponent of the 10.
So in this problem, you would move nine spaces to the left, so the exponent above the 10 would be a nine.
Therefore, the scientific notation would be:
4.4982529 x 10^9
