59 degrees

Step-by-step explanation:

so first things first you have the tringle it has a right angle meaning that this triangle will equal 90 degrees so here is what our equation would look like:

90=31+(3x-1)

So in order to solve this equation you must subtract add and divide.

First Rule in doing these equations: what you do to one side of the equal sign you do to the other side.

so we subtract 31 from 90 to equal 59 so the equation looks like this:

59=(3x -1)

you then add a one to the negative one and the 59 to get 60 making the equation look like this

60= 3x

we then divide 60 by 3 to get 20

so 20= x

But this is not our answer this is simply the solvation for x in (3x - 1)

so the equation now looks like this (3(20) - 1) and this equals 59 degrees

now to check our work!

31 + 59 = 90 or 90- 31 = 59
