Answer:
25°
Step-by-step explanation:
[tex]\alpha + \beta + \gamma = 180\\\\4x + 2x + 10 + x - 5 = 180\\\\7x = 180 - 5\\\\7x = 175 \\\\x = 175 / 7 = 25[/tex]
Answer: x=25
Step-by-step explanation: Add all of the coefficients together then subtract 5 from 10 then that answer from 180. Divide the final answer of the coefficients together then divide the two to get 25.
