Of the Aztec
Triple Alliance, which
tribe had the greatest
power?

Tenochtitlan became the center of power in the region.

Tenochtitlan

Explanation:

They divided the Tepanec lands among each other, creating the Aztec empire. The Triple Alliance expanded over the next hundred years until they ruled 5 to 6 million people. Although each city originally had equal power, Tenochtitlan soon emerged as the dominating force. It was the largest city by far in Mesoamerica, totaling over 140,000 citizens.

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°
