Given a right triangle, find the degree measure of the angles if one angle is ten degrees more than four times the degree measure of the other angle and the third angle is the right angle.

a right angle is 90 degrees

 the other 2 angles must equal 180-90 = 90 degrees

1st angle = x

 2nd angle = 4x+10

 add them together:

 x + 4x +10 = 90

 combine like terms:

5x +10 = 90

subtract 10 from each side:

5x =80

divide both sides by 5:

x = 80 /5 = 16

 1st angle = 16 degrees

 2nd angle = 4(16) +10 = 64 +10 = 74 degrees

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.
