Okay, so we’ll use sin in this case. You could use cos too, I just like sin. Sooo
sin(?) = 39/89
? = sin^-1(39/89) <— make sure you calculator is in degrees mode, not radians when doing this calculation!
? = 25.989° ≈ 26°
The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.



A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.

Answer:
a.
Vladivostok is three hours ahead of Bangkok.
Step-by-step explanation:
Time the train left Bangkok is 1:50am
It traveled for 16 hours 40 minutes.
If the train was to be in Bangkok.
The Time Will be 1+16 hours then 50+40 minutes
Which is 17 hours + 1 hour 30 minutes
Which is 18 hours and 30 minutes
And 18 hours = 6:00 pm
So if it was in Bangkok the time with be 6:30 pm
But in Vladivostok, it was 9:30 pm
It's clear that Vladivostok time is faster by 3 hours
If I counted the width and height right, then the volume of the rectangle is:
210 units^3
Hope this helps!
