Step-by-step explanation:
By Exterior Angle theorem,
80° + (6y + 3)° = (155 - 2y)°.
=> 6y + 83 = 155 - 2y
=> 8y = 72
=> y = 9.
Answer:
(6y + 3)° + 80° = (155 - 2y)°
6y + 3 + 80 = 155 - 2y
8y = 155 - 83
y = 9
m∠NML = <em>57°</em>
m∠NLK = <em>137°</em>
A
Volume of a cube = Length x Width x Height
Since all the sides are equal length you just need to cube it.
60 x 60 x 60
700,000
answer is 55° ..........
8 =x
2x+9=3x+1
Subtract 2x from each side
2x-2x+9=3x-2x+1
9 = x+1
Subtract 1 from each side
9-1 = x+1-1
