For number 5: 180 -139 = x
For number 6: x = 41
For number 7: x + 18 = 90 (not 100% sure)
For number 8: x = 72
For number 9: you could write an equation about an acute angle and divide it into 2 parts the have one side 3 + 8 and have the other x. Then you could go from there. I’m sorry if you can’t figure out number 9. I tried to think of something.
Answer:
The answer to this equation is 8
Step-by-step explanation:

<u>First: Subtract</u>

meaning that 5 is greater than 4.
You still need another number to make it equal than or greater than or equal to five.

Since 5 minus 4 does equal 1
You need somewhere to divide it from to get 1 so you can add up the 4 to it and get the answer to the equation.
<u>Lastly: Divide</u>


Now, if you do 8/8 which equals 1, 1+4 = 5; Now everything is, <u>equaled</u> up!
<u>So in conclusion...</u>
