Answer:
(x, y) = (18, 5)
Step-by-step explanation:
Assuming the three lines meet at a single point at lower left (the figure is sloppily drawn), the angle (3x)°+49° is a corresponding angle to (7x-23)°. That means they have the same measure:
3x +49 = 7x -23
72 = 4x . . . . . . . . . add 23-3x
18 = x . . . . . . . . . . . divide by 4
__
Angles (3x)° and (11y-1)° are "corresponding" angles, so are congruent.
3x = 11y -1
3(18) +1 = 11y . . . . add 1, fill in the value of x
55/11 = y = 5 . . . . divide by 11
The values of x and y are 18 and 5, respectively.
Has infinitely many solutions.
Answer:
110 students
Step-by-step explanation:
%40 Divide 30
30 divided by %40 is 0.75
SO there is 60% left
%60 divided by 0.75
That is 80
80 + 30 =
110
Answer:
y=34.5 degrees
x=17 degrees
Step-by-step explanation:
2y=69 because it is a corresponding congruent angle
y=34.5 degrees
2y=3x+18
69=3x+18
3x=51
x=17
