Need help

in early days people began using type of pots made of what ???

thats easy

Explanation:

they used this kind of metel it was brase and they used pans by an oak tree and they used these meterials to make what we have today is different but back then they did not have much so they had to use what they can find to make these things and they used to have to go to differnet places and contrys to find meteral such as these.

hpoe it 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°
