40 degrees because i just got it right, and shout out to cash carti!
For this case we use the formula of distance between points.
We have then:
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
For AB:
AB = root ((4 - (- 1)) ^ 2 + (4-3) ^ 2)
AB = 5.099019514
For AC:
AC = root ((8 - (- 1)) ^ 2 + (1-3) ^ 2)
AC = 9.219544457
For BC:
BC = root ((8-4) ^ 2 + (1-4) ^ 2)
BC = 5
We observe that it has three sides with different dimensions, therefore, the triangle is scalene.
Answer:
Scalene
This first picture is showing a total stack of blocks measuring 18 2/3 tall.
The stack is divided into 7 blocks that are 2 2/3 tall.
--> Second answer from bottom.
The next problem is a picture of a board that is 11 7/8 long. It is divided into 5 sections measuring 2 3/8 long.
-->3rd answer
Last problem is a picture of a rope that is 16 7/8 long. It is cut into 9 pieces that are 1 7/8 long.
--> 3rd answer
