What was the cause of Thomas Jefferson being elected?

Federalist James A. Bayard and his allies in Maryland and Vermont all cast blank ballots , this resulted in the Maryland and Vermont votes changing from no section to Jefferson giving him 10 states and the presidency

Explanation:

above

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

i think its provide for the common defense
