Find the value of X.

Step-by-step explanation:

The reason I say the answer above is wrong is because their answer equals up to a angle of 100 degrees however your angle is equaling up to 90 degrees. First off we know this angle is going to be 90 degrees right so we put it into the eqution:

=90

but we don't know what x is in order to solve the degrees that add up to 90, so since these equations add up to 90 we put them into the equation:

(3x + 5)+ (6x + 4) = 90

we then add all the numbers that have the same variables or are simply numbers in the equation

3x + 6x and 5 + 4 to get 9x + 9 = 90

we then subtract 9 from both sides (because what you do to one side you do to the other) to get 81

the equation now looks like this: 9x = 81 so now we divide 9 from both sides to get x = 9

Now how do we know if x is really 9 well we plug it into the equations (3x + 5) and (6x + 4) making them look like this (3(9) + 5) and (6(9) + 4)

and you get (3(9) + 5)= 32

                     (6(9) + 4)= 58

and when you add them together you get 90

32 + 58 = 90

Sorry it took so long to answer back. I hope this helps you
