Answer:
v = 17.4 meters
Step-by-step explanation:
This is a triangle with height (red dotted line) given.
The area of a triangle is given by the formula:

Where
A is the area
b is the base length
h is the height
Given height = 12, and
area = 104.4
THe base is labeled as "v", so we find v by replacing into formula:

The base, v, is 17.4 meters
180 miles per hour. 45*4 to get the answer.<span />
This has alot of information missing. Can you please repost this with more detailed information? Thanks.
Answer:
Each interior angle = 135 degrees,
Step-by-step explanation:
The exterior angles of all convex polygons add up to 360 degrees.
So for a regular octagon each exterior angle = 360 / 8
= 45 degrees.
Therefore each interior angle = 180 - 45 = 135 degrees,
