What were the major ideas in astronomy and mathematics developed by the maya and the aztec?

The Mayas made important breakthroughs in astronomy and mathematics.Language and Writing The Mayas developed the most complex system of writing in.They used hieroglyphics, or picture symbols, to represent sounds, words, and ideas.  One of the Aztecs' most remarkable technological achievements

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°
