How do I solve P=2L+2W for L

Natasha_Volkova [10]

You need to get L by itself. Keep in mind with equality problems that what you do to one side, you must do to the other.
Let me break it down for you.
P=2L+2W, -2w from both sides.
P-2W=2L, now divide the other side by 2.
1/2P-W=L

What does a=? b=? Angle B=?

Kobotan [32]

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

Answer:

$\large \boxed{\text{There is no solution}}$

Step-by-step explanation:

$\begin{array}{rcll}3x - 4 + 1 & = & -2x - 5 + 5x & \\3x - 3 & = & 3x - 5 & \text{Combined like terms on each side}\\-3 & = & -5 & \text{Subtracted 3x from each side}\\\end{array}\\\text{This is impossible. There is $\large \boxed{\textbf{no solution}}$ to the equation.}$
