Answer:
8
Step-by-step explanation:
Two or more lines are parallel when they lie in the same plane and never intersect. The symbol for parallel is <span>||</span>. To mark lines parallel, draw arrows <span>(>)</span> on each parallel line. If there are more than one pair of parallel lines, use two arrows <span>(<span>>></span>)</span> for the second pair. The two lines below would be labeled <span><span><span>AB</span><span>←→</span></span> || <span><span>MN</span><span>←→−</span></span></span> or <span>l || m</span>.
For a line and a point not on the line, there is exactly one line parallel to this line through the point. There are infinitely many lines that pass through A, but only one is parallel to l.
Df = g - 10
To solve for d, divide both sides by f.
df / f = (g - 10) / f
d = (g - 10) / f
I hope this explains it.

Answer:
<h3>
∠XYZ = 102</h3><h3>
</h3>
Step-by-step explanation:
<u>1st step is to solve x from ΔWXY</u>
∠W + ∠X + ∠Y = 180
where ∠W = 5x + 2
∠X = 7x + 4
∠Y = 180 - (15x - 18)
= 198 - 15x
now plugin values into the equation:
5x + 2 + 7x + 4 + 198 - 15x = 180
combine similar terms:
5x + 7x - 15x = 180 - 2 - 4 - 198
simplify:
-3x = -24
x = -24 / -3
x = 8
<u>2nd step is to substitute x = 8 into ∠XYZ</u>
∠XYZ = 15x - 18
∠XYZ = 15(8) - 18
∠XYZ = 102
