The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.

To find x, add the two angles together to equal 180:

7x + x+20 = 180

Combine like terms:

8x + 20 = 180

Subtract 20 from both sides:

8x = 160

Divide both sides by 8:

X = 20

Determine the value of x ? i’m so bad at math. sorry
sergij07 [2.7K]

Answer:

x = 50

Step-by-step explanation:

The legs are perpendicular and so the triangle is a right triangle.

Using the Pythagorean Theorem, we get

48^2 + 14^2 = x^2 = 2304 + 196 = 2500.  Then x is the positive square root of 2500, which is 50.  

x = 50

Find the instantaneous rate of change of the surface area s ! 6x2 of a cube with respect to the edge length x at x ! a
joja [24]

The instantaneous rate of change is simply equivalent to the first derivative of the equation or function. We are given the equation of Surface Area (A) with respect to side (x):

A = 6 x^2

Taking the first derivative of the equation:

dA = 12 x dx

dA / dx = 12 x

Now the term dA / dx is the instantaneous rate of change in the surface area with respect to the side length. To get the rate of change when the side x = a, simply plug this in into the equation:

rate of change = dA / dx = 12 x

so when x = a:

<span>rate of change = 12 a</span>
