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 ...
The appropriate choice is ...
B. 31°, 106°, 43°
well eric was correct because we have no measurements to use.
89.375 or 89.4 if rounded
715 divided by 8 = 89.375
check this by doing 89.375 x 8
hope this helps
x=4
divide the x-value by the y-value. 9/36 =0.25.
0.25*16=4
x=4.
