Total length of the board = 30 inch
Length of,
-- First piece = x
-- Second piece = 4x
-- Third piece = 5x
5x + 4x + x = 30
10x = 30
x = 3
Therefore, the lengths of:
-- First piece = 3 inch
-- Second piece = 4*3 = 12 inch
-- Third piece = 5*3 = 15 inch
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So since you are too lazy I assume that you already know what to do and you just don't want to do it so I don't think you'll need any explaining right?
X: -5 -1 0 1
_______________________________
Y: -32 -8 -2 4
sin = 3/7
1 = sin²0 + cos²0
cos²0 = 1 - 9/49
cos²0 = 40/49
cos0 = √(40) / 7
since its in Quadrant 2 the sin is positive and cos is negative
cos0 = - √(40) / 7
