In a right triangle the acute angles measure x+15 and 2x degrees what is the measure of the larger acute angle of the triangle

So, x+15 + 2x = 90 
Therefore 3x = 90 - 15 = 75 
and so x=25. 

So the smaller angles are x+15 = 40 degrees and 2x=50 degrees. 
So the larger one is 50 degrees.

your answer would be 10x - 1

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
