Answer:
a. 58
b. 35
Step-by-step explanation:
a. Given,
sinθ = cos 32
We know that cos x = sin (90 - x)
⇒ sin θ = sin (90 - 32)
⇒ sin θ = sin 58
⇒ θ = 58
Thus, the value of θ would be 58.
b. Given,
cosθ = sin(θ+20),
sin (90 - θ) = sin (θ + 20)
⇒ 90 - θ = θ + 20
⇒ 90 - 20 = θ + θ
⇒ 70 = 2θ
⇒ θ = 35
Thus, the value of θ would be 35.
1/5 of an hour is 12 minutes. 60 seconds x 12 minutes= 720 seconds
Answer: First, turn the mixed fraction 16 1/4 into a improper fraction. It would become 65/4
x+65/4=64
Next, I would multiply the entire equation by 4 to get rid of the fraction
It would become 4x+65=256
Now solve for X
4x=191
x=191/4
x=47.75

Answer:
3450 miles
Step-by-step explanation:
Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.
