In the given diagram:
measure angle DAB + measure angle BAC = 90 degrees
we are given that measure angle DAB = 10 degrees
Therefore:
measure angle BAC = 90 - 10 = 80 degrees
Now, triangle ABC is a right-angled triangle which means that we can use the trigonometric functions.
The function that we will use is:
cos theta = (adjacent) / (hypotenuse) where
theta = 80 degrees
adjacent = 500
hypotenuse is "x" that we want to calculate.
Substitute to get x as follows:
cos 80 = 500 / x
x = 500 / cos 80 = 500 / 0.1736 = 2879.4 m
Answer:
Let the number of student who plays both be x
then
(7-x)+x+(13-x)+13=29
33-x=29
x=4
the probability that a student who plays an instrument also plays a sport
= 4/29

A circle is 360* so I did 360-75. Hope this helps!!!
Answer:
1012
Step-by-step explanation:
Given:
pitch 'p' = 460 vibrations per second
wavelength 'w'= 2.2m
'k' represent constant of variation
'k' can be determined by taking the product of pitch and wavelength
k= p.w
k= 460 x 2.2
k= 1012
Therefore,
the constant of variation is 1012
145,300 X .2 = 29,060
you multiply .2 because that is equal to 20% in decimal form, and you are finding out how much the insurance covers
therefore your answer would be 29,060 dollars
