Step-by-step explanation:

☥ \underline{ \underline{ \text{Given} }}:

  • Total number of students = 50
  • Percentage of students who are wearing white shirts = 38 %

☥ \underline{ \underline {\sf{To \: find} }}:

  • Total number of students who are wearing white shirts

☥ \underline{ \underline{ \sf{Solution} }} :

⟹ \sf{38\% \: of \: 50} =  \frac{38}{100}  \times 50 =  \boxed{ \sf{19}}

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

What numbers multiply to equal -9 but add up to 12?
Elan Coil [88]
I don't think this is possible.

The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3

And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0

Sorry but there is not an answer. :(
