Question

I want to know how to find EF and what the answer is.

Answer 1

$\huge\underline\mathtt\colorbox{cyan}{37✅✅✅}$

Step-by-step explanation:

• 5x+12=6x+7 (opposite sides of a parallelogram are equal)
• 12=x+7 (subtract 5x from both sides)
• x=5 (subtract 7 from both sides)
• Now put x in any of the equations-- 5(5)+12=37 or 6(5) +7=37
