Answer:
Explanation:
As we know, that ALL triangles WILL totally equal to [tex]180^{0}[/tex]. So, in that way, we have to find the measurement of angles B and C. That will happen by adding...
43+15=
40+10=50
3+5=8
50+8=58
So, These two angles equal 58
Now, to find the angle of A, we have to subtract 58 with 180 degrees.
180-58=122
So, our answer is 122.
