how do I find x in an angle.

Question

so my test is in a few days but I don't know how to fund x in a problem that looks like this: 

 

43 degrees & (4x+3) degrees 

 

how is the easiest way up to find x in these kind of problems?

Answer 1

Emily,

 

I presume the problem is stating 43 degrees = 4x+3 degrees

 

In that case you equate 43 = 4x + 3

 

Subtract 3 from both sides 43-3 = 4x + 3 -3

or 40 = 4x

Divide both sides by 4

10 = x

 

Value of x is 10
