Solve for x<br>2x + 4 + 2x -9 + 8 = 180​
Alex

Answer: Simplifying

2x + 4 + 2x + 8 + 2x + 8 = 180

Reorder the terms:

4 + 8 + 8 + 2x + 2x + 2x = 180

Combine like terms: 4 + 8 = 12

12 + 8 + 2x + 2x + 2x = 180

Combine like terms: 12 + 8 = 20

20 + 2x + 2x + 2x = 180

Combine like terms: 2x + 2x = 4x

20 + 4x + 2x = 180

Combine like terms: 4x + 2x = 6x

20 + 6x = 180

Solving

20 + 6x = 180

Solving for variable 'x'.

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

Add '-20' to each side of the equation.

20 + -20 + 6x = 180 + -20

Combine like terms: 20 + -20 = 0

0 + 6x = 180 + -20

6x = 180 + -20

Combine like terms: 180 + -20 = 160

6x = 160

Divide each side by '6'.

x = 26.66666667

Simplifying

x = 26.66666667

What must be the length of ZY in order for ZY to be tangent
Nata [24]

Answer:

15 units

Step-by-step explanation:

The picture of the question in the attached figure

we know that

Triangle XYZ is a right triangle, because segment ZY is tangent to circle X at point Y

so

Applying the Pythagorean Theorem

XZ^2=XY^2+ZY^2

we have

XZ=8+9=17\ units\\XY=8\ units

substitute the given values

17^2=8^2+ZY^2

ZY^2=289-64\\ZY^2=225\\ZY=15\ units
