Answer:
first option
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin30° = , cos30° =
sin30° = = = ( cross- multiply )
2x = 32 ( divide both sides by 2 )
x = 16
----------------------------------------------------------
cos30° = = = ( cross- multiply )
2y = 32 ( divide both sides by 2 )
y = 16
Answer:
Pat earnings = $181
Ally earnings = $362
Julie earnings = $452
Step-by-step explanation:
Let
Pat earnings = x
Ally earnings = 2x
Julie earnings = 2x + 90
Total earnings = $995
Total earnings = Pat earnings + Ally earnings + Julie earnings
995 = x + 2x + (2x + 90)
995 = 3x + 2x + 90
995 = 5x + 90
995 - 90 = 5x
905 = 5x
x = 905/5
x = 181
Pat earnings = x = $181
Ally earnings = 2x
= 2(181)
= $362
Julie earnings = 2x + 90
= 2(181) + 90
= 362 + 90
= $452
