Step-by-step explanation:its yo mom
It would take the train 1 minute to pass through the tunnel.
1 ÷ 60 = 1/60 mph
1/60 mph also equals 1 min, since there are 60 min in an hour
Hope this helps!
Answer:
1.-
a) θ = 45 ° + 360k
θ = 135° + 360k
b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.-
a) θ = 30° + 360k
θ = 330° + 360k
b) θ = 30° 0 ≤ θ < 360°
θ = 330°
3.-
a) θ = 60° + 360k
θ = 240° + 360k
b) θ = 60° 0 ≤ θ < 360°
θ = 240°
Step-by-step explanation:
1) 2 sin θ = √2
sin θ = √2/2
1.a ) θ = 45 ° + 360k
θ = 135° + 360k
1.b) θ = 45 ° 0 ≤ θ < 360°
θ = 135°
2.
2 cos θ - √3 = 0
2 cos θ = √3
cos θ = √3/2
2.a θ = 30° + 360k
θ = 330° + 360k
2.b θ = 30° 0 ≤ θ < 360°
θ = 330°
3.- √3 cot θ - 1 = 0
√3 cot θ = 1
cot θ = 1 /√3
3.a θ = 60° + 360k
θ = 240° + 360k
3.b θ = 60° 0 ≤ θ < 360°
θ = 240°
The answer would be 6.2 then 7
