Answer:

  ∠S = 38°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so you have ...

  (x+17)° +(2x-2)° +(5x+5)° = 180°

  8x +20 = 180  . . . . .  divide by °, collect terms

  8x = 160 . . . . subtract 20

  x = 20 . . . . . . divide by 8

∠S = (2x -2)° = (2·20 -2)°

∠S = 38°

Write an equation in slope-intercept form for the line between (2,7) and (6, 19)

Answers

Answer:

y= 3x +1

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Gradient= [tex] \frac{y1 - y2}{x1 - x2} [/tex]

☆ (x1, y1) is the 1st coordinate and (x2, y2) is the 2nd coordinate

Using the formula above, slope of line

[tex] = \frac{19 - 7}{6 - 2} \\ = \frac{12}{4} \\ = 3[/tex]

Subst. m=3 into the equation:

y= 3x +c

To find the value of c, substitute a pair of coordinates.

When x= 2, y= 7,

7= 3(2) +c

7= 6 +c

c= 7 -6

c= 1

Thus, the equation of the line is y= 3x +1.

What is the length of arc S shown below? Enter an exact expression. The angle in the figure is a central angle in radians.

Answers

Answer:

The arc length  S = 11.304 cm

Step-by-step explanation:

Explanation:-

Given that the radius of the circle 'r' = 6 cm

Given that the central angle = [tex]\frac{3\pi }{5}[/tex]

The Arc length is defined by

                 S = r θ

                S = 6 × [tex]\frac{3\pi }{5}[/tex]

                [tex]S = \frac{18\pi }{5}[/tex]

               [tex]S = \frac{18(3.14) }{5}[/tex]      (∵ π = 3.14)

              S = 11.304 cm

The arc length  S = 11.304 cm
