Answer:
We know the triangle in a right triangle because of the pythagoras theorem: 5^2+12^2=13^2
25 + 144 equals 169, making it a right triangle since the equation works.
Step-by-step explanation:
I tried to explain this the best i could, hope it works :)
Convert rev/min to radians per min:
(7 rev/14 min) * (2pi rad/1 rev) = pi radian/min
Convert rad/min to rad/sec. This is the angular velocity:
(pi rad/min)*(1min/60 sec) = pi/60 rad/sec
Linear velocity = angular velocity * radius
(pi/60 rad/sec) * 30ft = 0.5pi ft/sec
Convert ft/sec to in/sec:
(0.5pi ft/sec) * 12 in/1 ft = 6pi in/sec

Answer:
5 1/3 ÷ 4 = 16/3
Step-by-step explanation:
basically what I did was 5 × 3 = 15 + 1 = 16/3
Answer:
4.0 meters, ∠C = 39°, ∠A = 51°
Step-by-step explanation:
Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the <em>Pythagorean Theorem</em> to solve for the height of the chain:
Now, we can use the <em>Law of Cosines</em> to figure out one of the acute angles:
∠C = 39°
And since we know that all angles in a triangle add up to 180°:
∠A + ∠B + ∠C = 180
∠A + 90 + 39 = 180
∠A = 180 - 90 - 39
∠A = 51°
