What type of art did rome give us, made up of small stones or pottery pieces to make one big picture?

Your answer is mosaic

Explanation:

The most detailed Roman mosaics use small stones to achieve an effect like brushstrokes. Especially in the eastern provinces of the Roman empire, artists “painted” with stone. Hope this helped :)

mosaic is the answer hope 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°
