Step-by-step explanation:

Draw a picture. The ladder is the hypotenuse of a right triangle with legs of length 6 ft and 8 ft.

length of ladder = √(6²+8²) = 10 ft

Answer:

<em>h = 8.54 units</em>

Step-by-step explanation:

<u>The Law of Cosines </u>

It relates the length of the sides of a triangle with one of its internal angles.

Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:

$c^2=a^2+b^2-2ab\cos x$

Since we know the values of all three side lengths, we solve the equation for x:

$\displaystyle \cos x=\frac{a^2+b^2-c^2}{2ab}$

For the triangle ABC in the image, a=10, b=15, c=13, thus:

$\displaystyle \cos A=\frac{10^2+15^2-13^2}{2*10*15}$

$\displaystyle \cos A=\frac{156}{300}$

$\displaystyle \cos A=0.52$

Thus, A = 58.67°

For the right triangle of height h and hypotenuse 10, we use the sine ratio:

$\displaystyle \sin 58.67^\circ=\frac{h}{10}$

Solving for h:

$h = 10\sin 58.67^\circ$

h = 8.54 units

Ms Rochelle wants to put 29 students into groups of 6. How many groups of 6 can she make ?

garik1379 [7]

Start by dividing 29/6, if you know your multiples you know 5*6 is 30, and since 29 is less than thirty, 29/6 has to be less than 5. since you can only have a whole number of groups, she can only make 4 groups of six
