You see two forms of a democracy: |Direct| in which the people directly vote and decide for themselves. As well as a |Representative| Meaning the people vote for others to represent them and act on their behalf.

Explanation:

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 believe the answer is d.
