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.

Quick Easy Eliminations:
We can get rid of positive integer as the sum of these roots is a decimal which is not a whole number. Hence, we can eliminate 2 options, C. Positive integer and D. Whole Number.
First solve:
6√14 + √14
= 7√14 (Decimal form: 26.191602)
What we need is the decimal form in order to determine if it's rational or irrational.
A rational number is any integer, fraction, terminating decimal, or repeating decimal.
