Answer:
x=7
Step-by-step explanation:
If one of the angles is a right angle, then it equals 90 degrees. Since the other angle is 33 degrees and all triangles equal 180 degrees, then that means that the remaining angle must equal 57. Since the angle that equals 57 degrees is represented by the expression 6x+15, then 57=6x+15 and now all that's left is to simplify:
[tex]57=6x+15\\57-15=6x+15-15\\42=6x\\\frac{42=6x}{6}\\7=x[/tex]
Hope this helps :)
