1) jovi is laying a foundation for a garage with dimensions 10m by 6m. to check that the foundation corners meet at 90 degrees angles, jovi measures a diagonal. how long should the diagonal be?

2) a sloped mountain road is 12.7 km long. it covers a horizontal distance of 8.9 m. what is the change in elevation of the road?

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
