Answer:
x=26
Step-by-step explanation:
2x+3x+50=180 add like terms
5x+50=180 subtract both sides by 50
5x=130 divide both sides by 5
x = 26
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 50 = 180
5x + 50 = 180 ( subtract 50 from both sides )
5x = 130 ( divide both sides by 5 )
