thx :D

Oops.

sin(theta) bigger than 1 is impossible xD

Summarizing the 2 answers above:

Theta is a Greek letter which can represent an unknown angle 

Example :\(sin \theta = \frac{3}{2}\)

1 x 5 x 12 = 60

3 x 4 x 5 = 60

1x 2 x 30 = 60

all we do is to make one number significantly bigger than the other two

first i will consider 1 as the first number

as we have to make the 3 numbers different, we make the second number the smallest possible factor of 60, which is 2

then we divide 60 by 2 and get the 30

The largest possible sum = 1 + 2 + 30 = 33

Just replace fractions with decimals or division

\(6.7345\times10^4\)

\(\sqrt\pi \)

is approximately 1.7724538509055159

the graph of 5x - 4y = 25 is shown here

a^2 + b^2 = c^2

Just remembering that triangles have 3 sides, that's the basics, right?

next think of a + b = c in your brain, easy?

then add the square to each term

a^2 + b^2 = c^2 complete :D

Hope this can help you

Sometimes you don't use a calculator and you get the answer.
