Solve to find the value of x.

x=12

Step-by-step explanation:

We know that a right angle is 90 degrees. So we can make the equation Now, we can solve fore X! We can combine 35 and 7 to make the equation . In order to isolate x we have to subtract 42 from both sides, getting us the equation Now, in order to isolate x we must divide each side by 4, getting us the equation .  To prove that x=12, we can subsitute x for 12.  This means that we can do which simplified, is 90=90, making x=12 true. Hope this helps :)
