Answer:
x = 5.2
Step-by-step explanation:
x/(13-x) = 2/3
3x = 2(13 - x)
3x = 26 - 2x
3x + 2x = 26
5x = 26
x = 26/5
x = 5.2
Pythagoras’ theorem
a^2 + b^2 = c^2
Where a and b are two sides on a triangle and c is the hypotenuse.
Rearrange to find one to the sides that isn’t the hypotenuse.
a^2 = c^2 - b^2
a^2 = 25^2 - 10^2
a^2 = 625 - 100
a^2 = 525
(square root)
a = √525
= 5√21
Answer: girl
Step-by-step explanation: I think that you’re a girl because usually I would say boy, but then they say, “Nope!”, do I think this is a really trick question because this can describe either a boy or a girl.
Option 1.
sin(2x) = 2sin(x)cos(x)
cos(2x) = 1 - 2sin(x)^2
