Answer:
The variable x is equal to 10 degrees.
Step-by-step explanation:
A triangle's angles, in total, must equal 180 degrees.
71 + 50 + (6x-1) = 180
71 +50 = 121
121 + (6x-1) = 180
6x - 1 = 59
6x = 60
x = 10
c
x+x=90
2x=90 ,x=45 ,∆BAD=45
no doubt it's 16 inches
$69.50
.60 + .60 + .60 + .60 + .60 = 3
72.50 - 3 = $69.50
