What is the purpose of a primary election? a. to choose electors for the electoral college. b. to choose a party's candidate for a general election. c. to choose which party's candidate will be on the ballot for a general election. d. to choose between the two top vote getters for the general election.

Option B.

Explanation:

To choose a party's candidate for a general election, is the right answer.

Primary elections are the method by which citizens can show their choice for the candidate of their party, or a nominee in general, in forthcoming general polls, provincial polls, or by-election, to narrow the arena of nominees. The origins of the primary elections can be determined to the progressive movement in the U.S., that intended to exert the authority of contestant nomination from party leads to the people.

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°
