Answer:

A. \displaystyle 56°

Step-by-step explanation:

180° = x° + [x + 68]°

180° = 68° + [2x]°

- 68° - 68°

__________________

\displaystyle \frac{112°}{2} = \frac{[2x]°}{2} \\ \\ 56° = x

Answer:

A. 56

Step-by-step explanation:

Since a parallel line is 180 degrees, all we do is x + x+68 = 180.

2x = 112 or x = 56

Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3
e-lub [12.9K]
The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
15 {x}^{2}  = 20x
Divide both sides by 15:
{x}^{2}  =  \frac{20}{15}   \\  \\  {x}^{2}  =  \frac{4}{3}
Take the square root:
x =  \sqrt{ \frac{4}{3} }  \\  \\ x =  \frac{2}{ \sqrt{3} }  \\  \\ x =  \frac{2 \sqrt{3} }{3}

GEOMETRY HELP WILL MARK BRAINLIEST
alisha [4.7K]

Answer:

x=8

z = 115

Step-by-step explanation:

65 and 13x - 39 are vertical angles so they are equal

65 = 13x - 39

Add 39 to each side

65+39 = 13x - 39+39

104 = 13x

Divide each side by 13

104/13 = 13x/13

8 =x

65 and z are supplementary angles because they form a straight line.  This means they add to 180

65+z = 180

Subtract 65 from each side

65+z-65 = 180-65

z = 115
