Question

Can someone pls help?

Answer 1

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.
