Answer:
x = 8
Step-by-step explanation:
40 + 6x + 2 = 90 {Complementary angles}
Combine like terms
40+ 2 + 6x = 90
42 +6x = 90 {Subtract 42 form both sides}
6x = 90 - 42
6x = 48 {divide both sides by 6}
6x/6 = 48/6
x = 8

Step-by-step explanation:
Answer:$1,079.1
Step-by-step explanation:
Cost of TV = $990
Sales tax = 9% of TV cost= 9/100 × 990

Total cost of TV will be calculated by cost of TV + sales tax
=$990 + $89.1
=$1,079.1
Hope this helps.
