Answer:

A. $\displaystyle 56°$

Step-by-step explanation:

180° = x° + [x + 68]°

180° = 68° + [2x]°

- 68° - 68°

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:
$x = \sqrt{ \frac{4}{3} } \\ \\ x = \frac{2}{ \sqrt{3} } \\ \\ x = \frac{2 \sqrt{3} }{3}$

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
