Answer:
None of these
Step-by-step explanation:
The two cases are for trigonometry special angles.
The cosine of an angle is given as the adjacent side length divided by the hypotenuse side length
Cos ∅ = A/H
1. The case of 45°,45°,90°
Cos x = 1 /√2
2. The case of 30°, 60° ,90°
Cos x = 1/2 or √3/2
Answer: The equation that would help members to find how much they would pay per month is
40 + 12x = 460
Step-by-step explanation:
Let x represent the amount of money that members would pay per month.
Let y represent the number of months for which a member uses the gym.
There is a fee of $40 when you join, and the rest is paid monthly. This means that the cost of using the gym for x months would be
40 + xy
A one year membership to metro gym costs $460. Therefore are 12 months in a year. Therefore,
40 + 12x = 460
12x = 460 - 40 = 420
x = 420/12 = 35
The equation that would help members to find how much they would pay per month is
Answer:
55°
Step-by-step explanation:
d = 180 - 80 = 100
100 + 130 + 90 + (180 - 85) + (180 - c)
= 540
595 - c = 540
c = 595 - 540
c = 55°
