Which of the following people was not a candidate in the 1824 presidential

election?

(a) john quincy adams

(b) john c. calhoun

(c) henry clay

(d) william crawford

(e) andrew jackson

Explanation:

The correct answer is B)John C. Calhoun.

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°
