Answer:
<em>∠6 = 78°.</em>
Step-by-step explanation:
<em>∠3 = 78°</em>
<em>∠2 and ∠3 are vertical angles, => ∠2 = ∠3 = 78°.</em>
<em>∠2 and ∠6 are corresponding angles, => ∠6 = 78°.</em>
If the length of the rectangle is 6 and the perimeter is 54, multiply the length by 6 and subtract the answer from 54. Then, divide the answer by 2 to get the width.
So, I will use your formula for this as it is correct:
2l+2w=54
2(6)+2w=54
12+2w=54
2w=42
42/2=21
w=21
Therefore, your length is 21. Hope this helps!
