a. declare war on nation
b. collect taxes from citizens
c. trade with foreign countries
d. print currency and control banks

The correct answer is letter B.

Explanation: The tax is a mandatory tax levied by the government. This means that it is an amount that you pay and contributes to defray the administrative expenses of the state. Payment cannot generate fines and even legal punishment.

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°
