To evaluate cot θ given that sinθ=√6/5 we shall have:
sin θ=opposite/hypotenuse
hence
opposite=√6
hypotenuse=5
thus the adjacent will be found using the Pythagorean theorem
c²=a²+b²
plugging in the value we get:
5²=(√6)²+b²
b²=25-6
b²=19
b=√19
thus
adjacent=√19
but
cotθ=1/tanθ
tanθ=√6/√19
hence:
cotθ=√19/√6
Answer:
I think C
Step-by-step explanation:
Step-by-step explanation:
when the scale says 1:500000, then that means 1 unit in the map corresponds to 500000 units in reality.
and so, 3.2 cm on the map are
3.2 × 500000 cm in reality.
3.2 × 500000 = 1,600,000 cm = 16,000 m = 16 km
Answer:
Not sure if this is right, but I got $40.8.
Step-by-step explanation:
I first turned 20% into a decimal. (0.20).
Then I multiplied 0.20 and 34 which is 6.8.
I then added 34 since it’s the original cost to 6.8 since that’s the tip amount.
After that, you should get $40.8.
