Since they are complementary 
 x + y = 90

Sin(o) = Cos (90-0) 

Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]

Angelica's salary this year is 14% higher than it was four years ago. If she earns $46,170.00 this year, what did she earn four
Alona [7]

Answer:

D. $39,706.20

Step-by-step explanation:

In this problem, you are subtracting 14%. A way you could do this is buy finding 14% of $46,170.00, then subtracting that from itself. Or instead, you could find 86%. This works because its like your subtracting 14% from the whole 100%. so 100 - 14 = 86.

Method 1:

$46,170.00 x 0.14 = 6463.8

$46,170.00 - 6463.8 = 39706.2

Method 2:

100 - 14 = 86

$46,170.00 x 0.86 = 39706.2

either way the answer is still correct. i hope this make sense and that it helps you!
