Find x. (Photo Attached Below) A B C D

Mathematics
1 answer:
Aloiza [94]3 years ago
8 0

Answer:

Using the trigonometric function sine, x is 18 (second option)

Step-by-step explanation:

x is the hypotenuse of the right triangle, because is the side opposite to the right angle (angle of 90°):

Hypotenuse: x=?

The given side of 9 is the opposite side to the given angle of 30°

The trigonometric function that relates the opposite side of an angle with the hypotenuse is the sine function:

sin Angle = Opposite side to the Angle / hypotenuse

Replacing the given values:

sin 30° = Opposite side of angle 30° / hypotenuse

sin 30° = 9/x

1/2=9/x

Solving for x: Cross multiplication:

(1)(x)=(2)(9)

x=18

Triple my number add six and subtract my number twice I get my number plus three
liberstina [14]
Let the number be x.

Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3

So, combining these into an equation, we get:
3x + 6 - x - x = x + 3

If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3

Therefore, this is a false statement.

I need some help please. Write a function rule to describe each statement...
hichkok12 [17]
You could see the pattern

it cost 3.8 cent to print 1 dollar,

It cost 2 x 3.8 cents to print 2 dollar

it cost 3 x 3.8 cents to print 3 dollar

First equation 
f(x) = 3.8 x

Same with second equation,
f(x) = 15x

for equation 3, it would be :

y = 1.50 x - 0.8x

Hope this helps
