Answer:
Note :
The perimeter is : AB + BC + CA
AB =√((XB - XA)² + (YB - YA)²) = √((16-2)²+(2-8)²) = √(12²+6²) = √(144+36)=√180
AB = √(36×5) = 6√5 units
same method for : BC ; CA ..........
Perimeter = 32.44 unit
Area of triangle = 30 unit²
Step-by-step explanation:
By distance formula distance between (a,b) and (c,d) is
So, we have
Perimeter = 15.23 + 10 + 7.21 = 32.44 unit
We have
Area of triangle
BDC 37°
CDE 143°
FDE 37°
FDA 90°
with a hope, this helps you!
4/5 is greater
60% = 60/100
4/5 = 80/100
80>60
The probability would be 4/15
