Hello!
We can solve this using trigonometric functions. We will be referring to the 70 degree angle. We need to solve for the hypotenuse. We have the length of the opposite side and need to find the hypotenuse. Therefore, we use the sine.
sin70=12/x
Since we cannot immediately solve for x, we will simplify this equation. We multiply both sides by x.
x(sin70)=12
Divide both sides by sin70.
x=12/sin70
Now we solve this equation.
12/sin70≈15.51
Therefore, x=15.51 cm.
I hope this helps!

Answer:
2 pounds = 0.9072 kilograms
Step-by-step explanation:
Answer:
y = 15 + 0.10x
y = 10 + 0.12x
Step-by-step explanation:
We'll use variable "x" to represent our minutes.
Frank's payment will always $15 no matter what, so there can't be a variable on it. Same with Josie & the $10.
For every minute, x, Frank pays an additional 10 cents with the $15.
For every minute, x, Josie will pay an additional 12 cents with the $10.
Because both equations equal y, we can set them equal to each other to find what value of x that their phone bills will be equal.
15 + 0.10x = 10 + 0.12x
5 = 0.02x
x = 250 minutes
Hope this helps. :)
