I think that the answer is clockwise 90. Hope it help?????
Answer:45.1%
Step-by-step explanation:
Answer:
37/100 is already simplified, as a decimal 37/100 is 0.37 and as a percentage 37/100 is 37%
Here's how you do it: you find all the distances between the three points and add them together to calculate the perimeter of the triangle. To calculate for the distance between two points, the formula is
d = √[(x2 - x1)² + (y2 - y1)²]
So, just take two points, assign x1 and x2 with corresponding y1 and y2, then you get the answer.
Points: D(1,4), E(3,-2), C(-3,1)
After substituting the answers would be:
DE = 6.3 units
CE = 6.7 units
CD = 5 units
Perimeter = 6.3 + 6.7 + 5
Perimeter = 18 units
