Answer:

122 degrees

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.

Angle A, measures 122 degrees.
