You have the opposite and the hypotenuse given. So you use the sine ratio
Sin x = 6/9
x= sin inverse of 6/9 = 41.8 degrees
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
I believe A should be the answer, hope that helps.
Answer:
2/3
Step-by-step explanation:
0.25/0.375=0.666666666666666666666667
C- y= 6x
This means you times the x by six to get your y- (2x6=12) (4x6=24)
Hope this helps
