Answer:
x = 10
Step-by-step explanation:
<u>Interior angles of a triangle sum to 180°</u>
Therefore, to find the value of x, sum the given angles, equal them to 180, then solve for x:
⇒ 6x + 8x + 4x = 180
⇒ (6 + 8 + 4)x = 180
⇒ 18x = 180
⇒ 18x ÷ 18 = 180 ÷ 18
⇒ x = 10
X= 10 degrees
all sides of a triangle add to 180
6x+8x+4x=180
18x=180
x=10
