BC= 8 cm
The measure of angle C is 90
Cos B = 8/15
Sin C = 1
Tan C = 15/8
Zero slope line coinciding with x axis and undefined slope line coinciding with y axis
We can find distances
Length of AB:
A=(-2,-2)
so, x1=-2 , y1=-2
B=(4,-2)
so, x2=4 , y2=-2
now, we can use distance formula
now, we can plug values
Length of CB:
C=(4,6)
so, x1=4 , y1=6
B=(4,-2)
so, x2=4 , y2=-2
now, we can use distance formula
now, we can plug values
Length of AC:
A=(-2,-2)
so, x1=-2 , y1=-2
C=(4,6)
so, x2=4 , y2=6
now, we can use distance formula
now, we can plug values
Length of DE:
D=(5,7)
so, x1=5 , y1=7
E=(5,1)
so, x2=5 , y2=1
now, we can use distance formula
now, we can plug values
Length of EF:
E=(5,1)
so, x1=5 , y1=1
F=(13,1)
so, x2=13 , y2=1
now, we can use distance formula
now, we can plug values
Length of DF:
D=(5,7)
so, x1=5 , y1=7
F=(13,1)
so, x2=13 , y2=1
now, we can use distance formula
now, we can plug values
now, we can compare them
now, we can draw both triangles
Since, sides of both triangles are equal
so, by using SSS rule
triangle ABC and triangle DEF are congruent
so, this is TRUE........Answer
Answer:
B?
Step-by-step explanation:
I think the answer is B sorry if I'm wrong.
That the number would have a decimal or it could be a fraction
