If a = 50 degree, b = 60 degree, prove that A,B, and c are all of the first quadrant.

If A 50 Degree B 60 Degree Prove That AB And C Are All Of The First Quadrant class=

Sagot :

Given the following question:

a = 50 degrees

b = 60 degrees

To find which quadrat a angle lies we use a graph

We know that the top of the graph is at max 90 degrees and that the angles are positive so 50 and 60 degrees would indeed be within the first quadrat.

Now at most a triangle will equal 180 degrees and since we already have two of the angles we can just...

[tex]\begin{gathered} 50+60=110 \\ 110+70=180 \end{gathered}[/tex]

c = 70 degrees

So knowing that the top of the graph is at max 90 degrees and that all the following angles are below 90 degrees and are positive (which means all three angles will go in the top right direction). We know that angles A, B, and C are all apart of the first quadrant.
