Find y. right triangles

Juli2301 [7.4K]

Answer:

√2

Step-by-step explanation:

Angle ( θ ) = 45

Hypotenuse side = 2

Opposite side = x

Formula : -

sin θ = Opposite side / Hypotenuse side

Note :

The value of sin 45 = 1/√2

sin 45 = x/2

1/√2 = x/2

Cross multiply,

x*√2 = 2*1

x√2 = 2

2 can be simplified as √2 * √2

x√2 = √2*√2

Divide √2 on both sides,

x = √2

If you have a quarter of a pie and you cut it in half, what fraction of a pie would each slice represent? enter the numerator fo

yarga [219]

$\\
\text{Suppose you have a quarter of a pie, so in mathematical notation the part of }\\
\text{pie you have is}=\frac{1}{4}\\
\\
\text{now you cut this piece of quarter pie in half and make two equal part.}\\
\\
\text{so the fraction of the pie, that each slice would represent is:}\\
\\
=\text{Half of the quarter pie}\\
\\
=\frac{1}{2}\left ( \frac{1}{4} \right )\\
\\
=\frac{1}{8}$

Hence the fraction of a pie that each slice represent is: 1,8
