The length of each side of a square was decreased by 2 inches so the perimeter is now 49 inches. What was the original length of

aleksley [76]

The Original length of each side of square was 14.25 inches.

Step-by-step explanation:

Perimeter of a square is given by:

Perimeter = 4 * side

Let x be the original length of each side of square

decreasing 2 inch will mean

$x-2$

Perimeter of square after reducing 2 inches from each side

$4(x-2) = 49\\4x-8 = 49\\4x = 49+8\\4x = 57\\\frac{4x}{4} = \frac{57}{4}\\x = 14.25$

So,

The Original length of each side of square was 14.25 inches.

Tan39= x/68<br> Plz help. Will give brainliet

lesya [120]

Answer:

$\huge\boxed{x \approx 55}$

Step-by-step explanation:

We need to note that this is an equation, in which we can solve for x.

$tan(39) = \frac{x}{68}$

We can use a calculator to find the tangent of 39 - we type 39 into the calculator then press the "TAN" button to find it's tangent. We find that to be around 0.81.

We now have the formula simplified down to $0.81 = \frac{x}{68}$ . To solve for x, we want to isolate it on one side, so we can multiply both sides by 68 to get rid of the fraction.
