Why and how the mexican revolution start

The Mexican Revolution started in 1910, when liberals and intellectuals began to challenge the regime of dictator Porfirio Díaz, who had been in power since 1877, a term of 34 years called El Porfiriato, violating the principles and ideals of the Mexican Constitution of 1857.

Explanation:

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°
