6\sqrt2

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2

In general, the formula for calculating the hypotenuse in an isosceles right triangle is h=a\sqrt2

a - a leg, h - a hypotenuse

The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,





c=2pir
a=pir^2

c=2pir=16pi
divide both sides by 2pi
r=8

a=pir^2
a=pi8^2
a=pi64
a=64pi in²

Pretty lost WILL GIVE FIVE STARS
Artemon [7]

Being able to do this problem hinges mainly on your knowing the definitions of the trig functions and being able to read side lengths from the given diagram.

csc theta = hypotenuse / opp side = 4 / √(4^2 + 5^2) = 4 / √41.

sin theta is the reciprocal of csc theta, or √41 / 4.

cot theta is adj side / opp side = 5/4.

The sum of 3 consecutive odd numbers is 183. what is the second number in this sequence?
Juliette [100K]
Let, the numbers are: x, (x+2), (x+4)
Now, x+x+2+x+4 = 183
3x + 6 = 183
3x = 177
x = 59

So, second number would be: (x+2) = (59+2) = 61

In short, Your Final answer would be 61

Hope this helps!
