You can get this by multiplying the two numbers together which will give you 10/30. That can then be simplified.
OK so we know that the other side is 12 because the right triangle has to have two sides that add up to the hypotenuse, and I believe it gives you the answer in the question because you are trying to find x which it says x is the angle, and since its a right triangle, it would be 90°
It took 8 weeks because follow 15 to the dot then go down and you see the answer
Is there more to the question? I’m confused on the content. Maybe a chart you forgot to post or something
