What is m Please help me

Answer:
Angle BCA = 70
Angle CAB = 20
Step-by-step explanation:
Not sure what angle you meant, so I'll give you all of them <3
Angle BCA = 70 degrees, because If two angles form a line, they add up to 180. (110+x=180, x = 70)
Angle CAB = 20 degrees, because there are 180 degrees in a triangle, so 90+70+x=180, x = 20
Hope it helps <3
Answer:
BCA = 70
CAB = 20
ABC=90
Step-by-step explanation:
ABC is 120 because the square indicates that
BCA = 70 because angles on a straight line add up to 180.
110+x=180
x=180-110
=70
Angle CAB = 20 degrees, because angles in a triangle add up to 180
90+70+x=180
x = 180-(90+70)
=180-160
=20
