Answer: 3 and 5 are supplementary angles, and 1 and 4 are vertical angles.
Depreciation = (Cost - Residual)/Useful Life
Cost = $48,000
Residual = $9,000
Useful Life = 15 years
Depreciation = (48,000-9,000)/15
Depreciation = 39,000/15
Depreciation = $2,600
The refrigerator will depreciate at $2,600 a year.
Answer:
∠A= 80°
Step-by-step explanation:
if they are supplementary then put them equal to 180
7x + 3 +7x + 23 = 180
14x + 26 = 180
14x = 154
x= 11
now plug in
7(11)+3
77+3= 80
Simply divide with your calculator
18049/14 ≈ 1289.214
≈ 1289.214
Move all terms not containing x to the right side of the inequality.
x ≥ 13
Hope this helps! :)
and Happy Holloween!
