Sagot :
Answer: X = 12, Y = 5
Step-by-step explanation:
4x-27 = x+9
+27 +27
4x = x + 36
-x -x
3x = 36
3x/3 = 36/3
X = 12
3y + 19 = 11y - 21
+21 +21
3y + 40 = 11y
-3y -3y
40 = 8y
40/8 = 8y/8
Y = 5
The values of x and y are 12 and 5, respectively
The given parameters are:
- EH = 4x-27
- FG = x + 9
- EG = 3y + 19
- FH= 11y - 21
The slant sides of an isosceles trapezoid are equal.
So, we have:
[tex]EH =FG[/tex]
This gives
[tex]4x - 27 = x + 9[/tex]
Collect like terms
[tex]4x - x = 27 + 9[/tex]
[tex]3x = 36[/tex]
Divide through by 3
[tex]x = 12[/tex]
Also, the diagonals of an isosceles trapezoid are equal.
So, we have:
[tex]EG = FH[/tex]
This gives
[tex]3y + 19 = 11y - 21[/tex]
Collect like terms
[tex]11y - 3y =19 + 21[/tex]
[tex]8y = 40[/tex]
Divide through by 8
[tex]y = 5[/tex]
Hence, the values of x and y are 12 and 5, respectively
