Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
Answer:
I think it would cost $13,400
Step-by-step explanation:
if you do 320 times 335 you get 107200 and then if you divide that by 107,200 you get $13,400
Answer:
A. 270
Step-by-step explanation:
30% can be rewritten as 3/10
To multiply 900 by 3/10, just divide by 10 (90) and multiply by 3 (270)
Therefore, the answer is A. 270
Bonus: To find the actual price, just subtract this amount (270) from the original price (900).
The television costs $630.
Step-by-step explanation:
Subtract 5/8 on both sides
To subtract 5/8 we make the denominators same
Addition or Subtraction property of order is used
Subtract 4x on both sides
Addition or Subtraction property of order is used
Now divide both sides by -1
Multiplication or Division property of order is used
