Can play guitar and piano-=17 >top left
Can play guital total= 39 > top right
Which mean
Can play guitar but cant play piano= 39-17=22 > top middle

There were 8 students who could not play the guitar but knew how to play the piano.
Can play piano but can't play guitar= 8 >middle left
Can play piano total= 8 + 17= 25 >bottom left

There were 3 students who knew neither guitar nor piano
Did not know the guitar and piano=3 >middle middle

The answer would be:
Knew pianoDid not know pianoTotal
Knew guitar172239
Did not know guitar8311
Total252550

Answer from: iamasia06

knew piano did not know piano total

knew guitar 17 22 39

didnot know guitar 8 3 11

total 25 25 50

step by step solution:

Jake found that 39 students in his school could play the guitar and 17 of those students could play the piano, as well.There were 8 students who could not play the guitar but knew how to play the piano.There were 3 students who knew neither guitar nor piano.

Hence the total number of people who knew to play guitar is:

and those who do not know how to play guitar is: 8+3=11

The total number of people who knew to play piano is: 17+8=25

and the total number of people who do not know to play piano =(39-17)+3=22+3=25.

The table of the following information could be given as:

knew piano did not know piano total

knew guitar 17 22 39

didnot know guitar 8 3 11

total 25 25 50

Answer from: Quest

answer: $\frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}$

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

$\frac{sin40^{\circ}}{x} = \frac{sin60^{\circ}}{12}$

which is the required equation for finding the value of x,

$\frac{x}{sin40^{\circ}}= \frac{12}{sin60^{\circ}}$

$x= 12\times \frac{sin40^{\circ}}{sin60^{\circ}}$

$x= 12\times 0.74222719896$

$x= 8.90672638762\approx 8.967$
