Answer:
<A= 65 & <B=78
Step-by-step explanation:
this is because first we must find X, so in order to do so we must add together all angle measures, then make that equal 180. So
(2x-9)+(2x+4)+x=180
2x+2x+x-9+4=180
5x-5=180
5x=180+5
5x=185
X=185/5
x=37
Then we just have to plug in the value of x into the angle measurements.
