If you could speak to anyone throughout history, who would
it be and why?

Hitler

Explanation:

i would choose Adolf Hitler because, i would like to know what made him believe that Jews were different from other beliefs also considering the fact that he was Jewish. I would also ask him how he gained the power he did in such a little period of time.

hope this helps :)

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°
