If EFGH is a rhombus, then the diagonals are perpendicular. Therefore m∠FDG = 90°.
Therefore we have the equation:
3x + 12 = 90 <em>subtract 12 from both sides</em>
3x = 78 <em>divide both sides by 3</em>
Answer:
x=26
Step-by-step explanation:
fdg is a 90 degree angle. 3x+12 3x26=78 78 plus 12 equals 90
Here you go with your correct answer
n/-5 - 9 = 2
move -9 to the other side
sign changes from -9 to 9
n/-5-9+9=2+9
n/-5=2+9
n/-5=11
multiply both sides by -5/1 to find n
(n/-5)(-5/1)=11(-5/1)
n=-55
answer: n=-55
