Answer:
m∠ABC = 74
Step-by-step explanation:
The sum of the measures of three angles of any triangle is invariably equal to the straight angle, also expressed as 180 °
So you subtract the given measurements of ∠BAC (76°) and ∠ ACB (19°) from 180. 180-76-19 = 74
The measurement of angle ABC is 74°

Answer:
x= -8
Step-by-step explanation:
2x+3x-12=8x+12
5x-12=8x+12
5x-8x=12+12
-3x=24
24/-3
x= -8
