How do i find what “x” equals? ? this is due very very

In the question, we are given a right triangle, meaning that the place where there is a square like angle is equal to  degrees. Since we know the values and expressions for all three angles, we can use the triangle sum theorem to make them all equal to  degrees. We get . First, we can combine like terms on the left-hand side of the equation. Doing this, we get . After we do this, we subtract , so we can slowly start to isolate the variable we are solving for, . This gives us , and when we divide by , we get , which is our answer. Hope this has helped and have a fantastic day!
