Answer:
A. csc θ=1/sinθ
Step-by-step explanation:
From SOHCAHTOA,
sine = opposite/ hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
In a right angled triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the side opposite the angle. This is the inverse of sine , therefore:
Csc Ф = 1/ sinФ

So,
All we have to do is multiply the amount of water Andy carried by the fractional amount he drank.
1/2 * 2/3
This is pretty simple. To halve TWO-thirds, just halve the numerator, since it's such a nice number.
Presto. Half of two is one.
Therefore,
1/2 * 2/3 = 1/3
Andy drank 1/3 gallons of water on his hike. That's 5 1/3 cups of water. I would estimate his hike to be about 3 miles. Easy peasy.
Answer:
Isosceles triangle
Step-by-step explanation:
Length of side AB = 
= 
= 
= 
= 4
Length of BC = 
= 
= 
Length of AC = 
= 
=
Since, AC = BC, ΔABC will be an isosceles triangle.
Sum of infinite series of a GS is a1 / (1-r)
so here it is 65 / (1 - 1/6) = 65 / 5/6 = 65*6 / 5 = 78 answer
