Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = 
, sin30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
× = 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Answer:
260.5
Step-by-step explanation:
The equation you would use to find her earning for the week would be:
y=0.03(x-1000)+150
This would mean she made $66 from commissions and $216 total.
The equation of a line in point-slope form is y-6=1/3(x-2) remember point-slope is y1-y2=m(x1-x2)
