Draw arcs on either side of a given point on the line
To construct a line perpendicular to another line through a point on the line:
Measure a length from that point to one edge of the line
Draw two intersecting arcs on either sides of the line
Draw a straight line from the intersecting point of the arcs to the point on the existing line.
The new line drawn is a perpendicular line.
The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"
Option C is the correct choice

Answer:
n + 10
Step-by-step explanation:
The answer is 52.5 miles away.
First, you need to divide 15 and 2 by 2 to get a unit rate: 1 cm = 7.5 miles.
Then you multiply both numbers by 7: 7 cm = 52.5 miles.
Hope this helps!
The measure of the exterior angle at vertex D is: D. 54°
<em><u>Recall:</u></em>
- The exterior angle theorem of a triangle states that the measure of an exterior angle equals the sum of the measures of two opposite interior angles of the triangle.
<em><u>Thus:</u></em>
In ΔDEF, (8x−2)º is an exterior angle at vertex D.
m∠E = (3x−8)° (interior angle)
m∠F = (4x+13)° (interior angle)
<em>Therefore:</em>
(8x−2)º = (3x−8)° + (4x+13)°
8x - 2 = 3x - 8 + 4x + 13
8x - 2 = 7x + 5
8x - 7x = 2 + 5
x = 7
Exterior angle at vertex D = (8x−2)º
= 8(7) - 2
= 54º (option D)
