Answer:
The correct option is A.
Step-by-step explanation:
It is given that DEFG is a parallelogram.
Draw the diagonals DF and EG. Place point H where DF and EG intersect.
In triangle HGD and HEF
,
∠HGD ≅ ∠HEF (Alternate Interior angle)
∠HDG ≅ ∠HFE (Alternate Interior angle)
By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.
DG ≅ EF (Opposite sides of parallelogram)
According to ASA postulate, two triangles are congruent if any two angles and their included side are equal in both triangles.
So, by using ASA criterion for congruence we get,
ΔDGH ≅ ΔFEH
Since corresponding sides of congruent triangles are congruent, therefore
GH ≅ EH (CPCTC)
DH ≅ FH (CPCTC)
Option A is correct.
Answer:
Step-by-step explanation:
In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.
Turn the notations into their number form:
The exponent is positive so move the decimal point to the right:
Do the same with the second notation:
Since the exponent is positive move the decimal point to the right:
Now multiply:
Now turn the number into scientific notation:
Hope this helps.
