Answer:
1 is 28, 2 is -133, 3 is 161
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.
360*160=57600
57600*17=97920
I think its 97,920
So if y= 7 you plug in the variable into the equation.
3(7-5)
3(2)
6
The answer is 6. I hope this helps love!:)
I believe it might be that x would be negative six. A triangle is supposed to sum to 180 degrees. An equation could be 180 = 52 + 78 + 56 + x.
