X + 6 + x + 8 + x = 53
3x + 14 = 53
3x = 39
x = 13 and the other 2 pieces are
19 and
21
Answer:
x = 3
Step-by-step explanation:
49 - 19 = 30
-2x - 12x = 10x
30 / 10 = 3
1+sin²x=2-cos²x
Remenber: sin²x+cos²x=1 ⇒sin²x=1-cos²x
1+sin²x=1+(1-cos²x)=2-cos² x (this is true)
Hello, sorry can’t help with that. i guess that’s just the way you are.
