All angles in a triangle add up to 180 degrees. Make all the angles in this triangle add up to 180 in an equation to solve for x.
(4x + 7) + (11x - 9) + 32 = 180
Combine like terms. (4x + 11x) and (7 - 9 + 32)
15x + 30 = 180
Subtract 30 from both sides.
15x = 150
Divide both sides by 15.
Graph B is the correct answer.
Answer:
A, C and D are continuous
Step-by-step explanation:
A is a set of any number x which 30 < x <=45
B is a set that contains only 3 and 7
C is a set of any number x which 60 <= x < 100
D is a set of any number x which -infinity < x < + infinity
E is a set that contains only even whole numbers
A continuous data set is a quantitative data set representing a scale of measurement that can consist of numbers other than whole number, like decimals and fractions.
