Answer:
The value of x = 2 it done by simplification method
Your height to the problem would 18mm you would just take 612/34=18
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
Answer:
QBO=12 degrees
Step-by-step explanation:
angle QAO=angle OAS so:
2x+6=4x-12
reducing:
2x=18
x=9
substituting x into QBO=3x-15 then:
angle QBO=3(9)-15=12 degrees
