Step 2 Add:25+25=50 50+5=55
Step 3 Check:30+25=55
The measure of the m∠IUV using the addition postulate is equivalent to 82 degrees
<h3>Lines and angles</h3>
A line is defined as the shortest distance between two points while an angle is the point where two lines meet.
Given the following measure of angles
m∠TUI = 65° and
m∠TUV = 147°
Required angle
m∠IUV
Using the addition postulate below
m∠TUV = m∠TUI + m∠IUV
Substitute the given parameters
147 = 65 + m∠IUV
m∠IUV = 147 - 65
m∠IUV = 82 degrees
Hence the measure of the m∠IUV using the addition postulate is equivalent to 82 degrees

Answer:
28 - 4x
Step-by-step explanation:
![18 -2 [x + (x - 5)] \\ = 18 - 2 [x + x - 5] \\ = 18 - 2 [2x - 5] \\ = 18 -4x + 10 \\ = 28 - 4x \\](https://tex.z-dn.net/?f=18%20-2%20%5Bx%20%2B%20%28x%20-%205%29%5D%20%20%5C%5C%20%20%3D%2018%20-%202%20%5Bx%20%2B%20x%20-%205%5D%20%20%5C%5C%20%20%3D%2018%20-%202%20%5B2x%20-%205%5D%20%5C%5C%20%20%3D%2018%20-4x%20%20%2B%2010%20%5C%5C%20%20%3D%2028%20-%204x%20%5C%5C%20)
