The centre of the stained glass window is in the shape of a regular polygon. What are the measures of the interior angle of the

tester [92]

Answer:

67.5 - 67.5 - 45 °

Step-by-step explanation:

Sum of INTERIOR angles of a polygon

(n-2) * 180 <====<u>ya just have to remember/know this !</u>

n is the number of sides n = 8 in this case

(8-2)*180 = 1080 ° < === this is the SUM of the 8 interior angles

EACH interior angle is then 1080 / 8 = 135 °

you can see from the picture that each of the two outside angles of the green triangle are 1/2 of this = 67.5° each

so the triangle measurements are

67.5 - 67.5 - 45 ( they have to sum to 180 for triangle)

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his

evablogger [386]

Answer/Step-by-step explanation:

a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as $y - b = m(x - a)$ , where,

m = slope, and (a, b) is a point on the line.

Using two points, (6, 12) and (3, 21), let's find slope, m.

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3$

Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in $y - b = m(x - a)$ .

✅Equation in point-slope form would be:

$y - 12 = -3(x - 6)$

Rewrite this to make it be in the slope-intercept form, $y = mx + b$ .

$y - 12 = -3(x - 6)$

$y - 12 = -3x + 18$

Add 12 to both sides

$y = -3x + 18 + 12$

$y = -3x + 30$

✅The equation in slope-intercept form is $y = -3x + 30$

b. ✍️Based on the linear model, $y = -3x + 30$ , the 30 represents b = y-intercept.

✅Therefore, it took Peter 30 mins long initially to deliver his package.

✍️Based on the linear model, $y = -3x + 30$ , "-3" represents the slope.

✅Therefore, Peter's delivery time decreased 3 mins per day.
