Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.

serg [7]

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

$\sin \theta =\dfrac{Perpendicular}{Hypotenuse}$

$\sin 60^\circ =\dfrac{x}{16}$

$\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}$

Multiply both sides by 16.

$\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16$

$8\sqrt{3}=x$

And,

$\cos \theta =\dfrac{Base}{Hypotenuse}$

$\cos 60^\circ =\dfrac{y}{16}$

$\dfrac{1}{2}=\dfrac{y}{16}$

Multiply both sides by 16.

$\dfrac{16}{2}=y$

$8=y$

Therefore, the missing side lengths are $x=8\sqrt{3}$ and $y=8$ .

Marcus has three dowels with the lens shown in the table complete the table to give each length in inches feet and yards

marin [14]

Remember there are 3ft in a yard and 12in. in a foot.

To convert 5.5ft to yd, divide by 3.

To convert 2.5yd to ft, multiply by 3 to get 7.5ft.

To convert 7.5 ft to in, multiply by 12.

Just remember when converting to a larger quantity (yards, for example) to a small (feet, for example), you multiply, and from smaller quantity to larger, divide.

Which values of a and b make the equation true? (2xy)^4 ---------- =4x^a (y^b) 4xy

hoa [83]

(2xy)^4=4x^a(y^b)4xy
16x^4y^4=16x^(a+1)y^(b+1)
4=a+1 4=b+1
3=a 3=b
