To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.

AB = x - 10, BC = x + 2, and AC = 28. Find BC.<br><br>Please help!

Leno4ka [110]

Answer:

BC = 20

Step-by-step explanation:

AC = AB + BC

28 = x-10 + x+2

Combine like terms

28 = 2x -8

Add 8 to each side

28+8 = 2x-8+8

36 = 2x

Divide by 2

36/2 = 2x/2

18 =x

We want to find BC

BC = x+2

=18+2

=20

You are running a concession stand selling hot dogs and sodas. Each hot dog costs $2 and each soda costs $1. At the end of the n

amm1812

Answer:

see the explanation

The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75

Step-by-step explanation:

Let

x ---> the number of hot dogs that were sold

y ---> is the number of sodas that were sold

we know that

You sold a total of 90 hot dogs and sodas combined

$x+y=90$ ----> equation A

You made a total of $105

$2x+y=105$

isolate the variable y

$y=105-2x$ ----> equation B

substitute equation B in equation A

$x+(105-2x)=90$

solve for x

$x=105-90\\x=15$

Find the value of y (equation B)

$y=105-2(15)=75$

therefore

The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
