Answer:
Ok, I did this unit a little while ago but I think I solved it:
Hyp = 16
Opp = 8
Adj = 13.856
0 = 30 degrees
Step-by-step explanation:
You were on the right track, with the sin = opp/hyp, you just have to follow the equation given. So if sin = 8/16, then opp = 8 and hyp = 16 due to the transitive theorem.
Now you have to use the pythagorean theorem for the third side (adj), so:
a^2 + 8^2 = 16^2
The answer would be around 13.856 (round to what's required.)
Finally, you have to find 0. basically, since you're finding an angle measure, use the inverse of sin. the equation would look like this:
sin-1(0)=8/16
so on your calculator, you should put:
sin-1(8/16)
the angle measure is 30, meaning its a 30 60 90 triangle.


Slope = 0 (The graph is a horizontal line that cuts the y at -2)
-------------------------------------------------------
Answer : Slope = 0-------------------------------------------------------
Lines b and c
they both go up 2 and over 1 (rise over run is slope)
Answer:
It is at 0 that mean that is the answer right?
Step-by-step explanation:
You can conclude that the sides are parallel because the slope of the opposites are the same. (Second option).
You can conclude that the polygon is a rectangle since it has 4 90º angles, and 4 sides, each one parallel to the other and of the same lenght as it's parallel. (Last option).
