sukhopar [10]

Answer:

$k=\frac{2P}{x^2}$

Step-by-step explanation:

The formula is $P=\frac{1}{2}kx^2$

We need to solve for $k$ , so we can perform the steps shown below:

$P=\frac{1}{2}kx^2\\P=\frac{kx^2}{2}\\2P=kx^2\\\frac{2P}{x^2}=k$

Hence, the third answer choice is correct.

Find the value of x and m∠HKL.

frosja888 [35]

Answer:

x = 25 degrees ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25
