WILL MARK BRAINLIEST Plot points A, B, and C, and draw a polygon, ΔABC, through the points. Draw a line perpendicular to through point B. Label the intersection of the line perpendicular to through B and point D. Measure and display the slopes of and . Display the equations of and in the Algebra margin. Measure and display the lengths of and . Calculate and display the area of ΔABC. Please screenshot your answer from geogebra and insert below

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
