HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Answer:

m∠A= 52 degrees

Step-by-step explanation:

(Every triangle equals 180 degrees)

First you have to find angle C.

Step 1- Subtract

180-105= 75  *The line is a 180 degree angle

Now that you have the measure for two angles, you subtract.

53+75+x=180

128+x= 180

-128     -128

x=52
