Answer:
<h2>15</h2>
Step-by-step explanation:
∠6 and ∠7 are Alternate Interior Angles.
The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.
m∠6 = m∠7 → 4x - 15 = x + 30 <em>add 15 to both sides</em>
4x = x + 45 <em>subract x from both sides</em>
3x = 45 <em>divide both sides by 3</em>
x = 15
The 3rd one cause at first its 1ft = 10ft and it was an 8 by 8 square and now its a 4 by 4 square meaning it was divided by 2 meaning you divide 10 by 2 getting 1ft = 5ft
