Answer:
B. 39°, 106°, 43°
Step-by-step explanation:
The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.
(3x +1) +(11x -4) +(5x -7) = 180
19x -10 = 180 . . . . . collect terms
19x = 190 . . . . . . . . add 10
x = 10 . . . . . . . . . . . divide by 19
__
Then the three angle measures are ...
- 3·10 +1 = 31
- 11·10 -4 = 106
- 5·10 -7 = 43
The appropriate choice is ...
B. 31°, 106°, 43°
Y = 3...I believe in standard form, this would be written as : y = 0x + 3
y = an integer is a horizontal line...and if u have x = an integer, it would be a vertical line
Answer:
90-61 is 29, x=29, you're welcome
Answer:
C = 20
Step-by-step explanation:
The sum of the angles of a triangle is 180
73+87+c =180
Combine like terms
160 +c = 180
subtract 160 from each side
160+c-160 = 180-160
C = 20
