The answer is 0.56464247339

Across from the right angle is the hypotenuse

Across from where the two long sides end is the opposite

And the other side is the adjacent

Sin (opposite/hypotenuse) cos(adjacent/hypotenuse) tan (opposite/adjacent)

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
