Answer:
3 * (f - 6) / 16
Step-by-step explanation:
Answer:

Step-by-step explanation:
If we take a look at the given picture, we can see that both sides are almost completely identical, so they must almost have the same value.
Let us do the plug in. Keep in mind that the angle is obtuse, meaning over 90 degrees, and angle identical or lower than 90 is incorrect.



True.


False. Meaning the 18 would not work.
x = 22.5

True.

False. Meaning that 22.5 does not work.
x = 30

True.

True. Meaning that 30 is the answer and can work.
x = 54

True.

False. Although the angle is larger than 90, 180 is a straight line, and we can see that the angles given are not straight lines or greater.
R=5.4
4.2r-12.68=10
+12.68 +12.68
4.2r=22.68
4.2/4.2 22.68/4.2
22.68/4.2= 5.4
Hope this helps! Have a great day :)
1. (3x-2)/4+1=5
2. (3x-2)/4+1-1=5-1
3. (3x-2)/4=4
4. (3x-2)/4+2=4+2
5. this is the mistake, wecan't just add them because the fractions aren't the same
(3x-2)/4 plus 2/1, the bottom numbers areen't the same
what should be done is go back to step 4 and mltiply both sides by 4, don't add 2
results in
5. 3x-2=16
6. 3x=18
7. x=6
