Identify one major reason for the United States' annexation of Hawaii.

None

Explanation:

The planters' belief that a coup and annexation by the United States would remove the threat of a devastating tariff on their sugar also spurred them to action. ... Spurred by the nationalism aroused by the Spanish-American War, the United States annexed Hawaii in 1898 at the urging of President William McKinley.

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°

what are the options ?
