If CJ=y+9 and JX=4y then y =3
Answer:
10 = 3 and 4
11 = 11 and 12
12 = 8 and 9
13 = 17 and 18
Step-by-step explanation:
Answer:
Step-by-step explanation:
formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x2 = 2
x1 = - 7
y2 = -6
y1 = - 6
Solution
d = sqrt( (2 - - 7)^2 + (-6 - - 6)^2 )
d = sqrt( 9^2 + (-6 + 6)^2 )
d = sqrt(9)^2
d = 9
The similarity ratio of ΔABC to ΔDEF = 2 : 1.
Solution:
The image attached below.
Given ΔABC to ΔDEF are similar.
To find the ratio of similarity triangle ABC and triangle DEF.
In ΔABC: AC = 4 and CB = 5
In ΔDEF: DF = 2, EF = ?
Let us first find the length of EF.
We know that, If two triangles are similar, then the corresponding sides are proportional.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Ratio of ΔABC to ΔDEF = 
Similarly, ratio of ΔABC to ΔDEF = 
Hence, the similarity ratio of ΔABC to ΔDEF = 2 : 1.
