Answer:
a
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan15° = 
= 
( multiply both sides by x )
x × tan15° = 20 ( divide both sides by tan15° )
x = 
≈ 74.6 ft ( to the nearest tenth of a foot )
Answer:
It's (D)
Step-by-step explanation:
Answer:
third choice is the answer r is greater than or equal to 46
Answer:
3,000. You take 15,000 and multiply by .4 to get how much she spent on rent (6,000). They you subtract the rent money from her total pay to get her money that she spent on living expenses, clothes and entertainment in total (9,000). Since she spent her money in six parts (3+2+1), you divide 9,000 by 6 to get 1,500 to get each part. Since for entertainment she has two parts you multiply 1,500 by 2 to get 3,000.
Set up an equation
1/2x+6=2/3x
Take all x's to one side & constants to other
1/2x-2/3x=-6
Subtract by getting a common denominator
-1/6x=-6
Divide both sides by -1/6
x=36
