Answer:

x = 1

Step-by-step explanation:

Triangle ABC is congruent to Angle DEF

13x - 12 = 7x - 6

6x = 6

x = 1

Answer:

x = 1

Step-by-step explanation:

These are congruent triangles

The single line is the same length in ABC as the single line in DEF

The double line is the same length in ABC as the double line in DEF

13x-12 is the same length as 7x-6

13x-12 = 7x-6

Subtract 7x from each side

13x-12 -7x =7x-6 -7x

6x-12 =-6

Add 12 to each side

6x-12+12 = -6+12

6x = 6

Divide each side by 6

6x/6 = 6/6

x = 6/6

x = 1

In parallelogram DEFG, DH = x + 5, HF = 2y, GH = 4x-3 and HE = 4y + 1. Find the values of x and y. The diagram is not drawn to s
GalinKa [24]
Rule: The diagonals of any parallelogram bisect each other. In other words, they cut each other in half.

This means DF is cut into two equal pieces: DH and HF.
Similarly, GE is cut into two equal pieces: GH and HE.

DH = HF
x+5 = 2y
x = 2y-5

GH = HE
4x-3 = 4y+1
4(x)-3 = 4y+1
4(2y-5)-3 = 4y+1 ... x has been replaced with 2y-5
8y-20-3 = 4y+1
8y-23 = 4y+1
8y-4y = 1+23
4y = 24
y = 6

If y = 6, then x is
x = 2y-5
x = 2(6)-5
x = 12-5
x = 7

Answers: 
x = 7 and y = 6
