Answer:

∠1 = 64°

∠2 = 116°

Step-by-step explanation:

Let x = supplement and x + 52 = the one angle. Set up this equation:

(x) + (x + 52) = 180

2x + 52 = 180

Subtract 52 from both sides.

2x = 128

Divide both sides by 2, and you get x = 64.

Keep in mind this equals the supplement. To find the measure of the other angle, add 52 and you get 116

slavikrds [6]

Answer:

Option 3

Step-by-step explanation:

Given data set is,

{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}

By using linear regression calculator,

Equation of the linear function will be,

y = 2x - 2

Therefore, Option 3 will be the correct option.

X-2y=18 2x+y=6 parallel perpendicular or neither

sergey [27]

<h3>Therefore they are perpendicular.</h3>

Step-by-step explanation:

A equation of line is

y =mx +c

Here the slope of the line is m.

Given equations are

x - 2y = 18

⇔-2y = -x +18

$\Leftrightarrow y =\frac{1}{2} x -9$ ............(1)

and 2x + y = 6

⇔y = -2x +6 ............(2)

Therefore the slope of equation (1) is $(m_1)$ = $\frac{1}{2}$

Therefore the slope of equation (2) is $(m_2)$ = -2

If two lines are perpendicular, when we multiply their slope we get -1.

therefore,

$m_1. m_2$ = $\frac{1}{2}$ . (-2) = -1

Therefore they are perpendicular.

avanturin [10]

Let S be the number of Brand S snowboards sold.
Let B be the number of Brand B snowboards sold.

309S + 489B = 4299
S + B = 11

S = 6 snowboards sold
B = 5 snowboards sold
