Please help I don’t understand how to do this!

We can solve this through algebra. So we know two of the angles already which means we can put them in the equation 22+41+3x=90

63+3x=90

Now that we have the equation above, we can solve this through basic algebra.

3x=27

divide both sides by three

x=9 is your answer

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
