In logarithm, inverse operations are applied.
The diagonals intersect perpendicularly, two consecutive angled are supplementary, and that opposite angles are equal
Solution:
we are given that
If G is the midpoint of FH, it mean that
we are also given that
So we can write
So
In order they are
1.1 * 10^12, 9.5 * 10^11 and 5*10^8
