1) Find the length of CB. CB is "opposite" to angle 45 deg and is the hypotenuse of triangle BCD.

CB = 6sqrt(2)*sin 45 deg = 6 sqrt(2) * (1 / sqrt(2) ), or:

CB = 6.

Recognize that x/6 = sin 30 deg, or x/6 = 1/2. Thus, 2x = 6 and x = 3 (ans).

I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGES.

For this case, the first thing we are going to do is add the number of students in each of the disciplines.
We have then:
walk = 9
bike = 8
skateboard = 3
Total: 20
The percentage sought is then:
(3/20) * (100) = 15%
Answer:
percentage of the total students chose skateboarding is:
D.) none of these

In a certain Algebra 2 class of 29 students, 5 of them play basketball and 16 of them play baseball. There are 10 students who p

ANSWER
$P(both\:sports)= \frac{2}{29}$

EXPLANATION
Let the number who plays both games be
$x$
Then those who play only basketball
$= 5 - x$

and those who play only baseball
$= 16 - x$

We were given that 10 students play neither sports.

We can then write the following equation,

$(5 - x) + x + (16 - x) + 10 = 29$

This implies that,

$- x + x - x = 29 - 5 - 16 - 10$

This simplifies to,

$- x = - 2$

This gives us,

$x = 2$

Therefore the number of students play both basketball and baseball is 2.

The probability that a student chosen from the class plays both basketball and baseball ball

$= \frac{2}{29}$
