Answer:
84m^2
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying height to the base
The height of the given parallelogram is 7m and the base is 12m
12 × 7 = 84
The answer for your question is number 2
So,
This is a simple subtraction problem: 7 - 2.
7 - 2 = 5

Hey there! I'm happy to help!
If angles are complementary, they add up to 90 degrees.
This gives us this system of equations.
J=K-18
J+K=90
We plug the value of J into the second equation to solve for K.
K-18+K=90
We combine like terms.
2K-18=90
Add 18 to both sides.
2K=108
Divide both sides by 2.
K=54
J is 18 less than K.
54-18=36
Therefore, angle J is 36 degrees and angle K is 54 degrees.
Have a wonderful day! :D
