Answer:
12
Step-by-step explanation:
you take the number 8 and then you add 4. and you find yourself with the answer 12
Tan(x) = 1/
We know that Tan 30 = 1/
Therefore, x = 30 degrees
Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.
y-7 = 15
y-7+7 = 15+7
y = 22 is the answer
