It's Pythagorean theorem.
a^2+b^2=c^2
a and b are the non hypotenuse sides.
so BC is 4 units and AC is 7 units
4^2+7^2=c^2
answer is √65 which is 8.06

Recognize this as an application of the Pythagorean Theorem.  The lengths of the sides are given:  base is 4 spaces and altitude 7 spaces, so the hypotenuse AC is sqrt( 4^2 + 7^2 ), or sqrt (65).  This is a little larger than 8.

Mekhanik [1.2K]
To answer the question above, use conversion factors and dimensional analysis. In this given, it is easier to use grams as the basis. 

a. (2 centrigrams) x (1 gram / 100 centigrams) = 0.02 grams
b. 2 grams 
c. (2 hectograms) x (1 gram / 0.01 hectogram) = 200 grams
d. (2 kilograms) x (1 gram / 0.001 kilogram) = 2000 grams
e. (2 milligrams) x (1 gram / 1000 millimeters) = 0.002 grams

Thus, the answer is 2 milligrams.
