Answer:
x = 6
Step-by-step explanation:
We can see that the the 32 degree angle plus the equation (9x + 4) is equal to 90 degrees.
We know this because the bottom line is a 180 degree angle, and we can see on the other side that it is a right angle.
If we were to turn that into an equation it would like like this:
(9x + 4) + 32 = 90
Now you just have to solve for x.
9x + 4 + 32 = 90
Combine like terms:
9x + 36 = 90
Subtract 36 from both sides
9x = 54
divide both sides by 9
x = 6
and you are left with the answer.
Answer:
Group the like terms
6x + 3x - x + 9
Work out the x values together and then add the 9
9x - x + 9
8x + 9
your final answer should be about 8x + 9 as it cannot be simplified anymore
