X°+(x+30)=180°<br>I need answer​
djyliett [7]

Answer:

210 + -1x

Step-by-step explanation:

Simplifying

X + (x + -30) = 180

Reorder the terms:

X + (-30 + x) = 180

Remove parenthesis around (-30 + x)

X + -30 + x = 180

Reorder the terms:

-30 + X + x = 180

Solving

-30 + X + x = 180

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '30' to each side of the equation.

-30 + X + 30 + x = 180 + 30

Reorder the terms:

-30 + 30 + X + x = 180 + 30

Combine like terms: -30 + 30 = 0

0 + X + x = 180 + 30

X + x = 180 + 30

Combine like terms: 180 + 30 = 210

X + x = 210

Add '-1x' to each side of the equation.

X + x + -1x = 210 + -1x

Combine like terms: x + -1x = 0

X + 0 = 210 + -1x

X = 210 + -1x

Simplifying

X = 210 + -1x

The formula for Area of a circle is

A=\pi r^{2} \\A=\pi 6^{2} \\A=113.097

That would be for the entire circle, now divide that number by .75 to get 3/4 of the circle.

What are the intercepts of 2x+5y-4z=40
statuscvo [17]
In order to find x-axis interception coordinates you need to set other two variables (y and z) to zero and solve the remaining equation.

So the following simple equations need to be solved:
2x = 40
5y = 40
-4z = 40

It intercepts x-axis at coordinates (20;0;0), y-axis at (0;8;0) and z-axis at (0;0;-10).
