The sum of the interior and exterior angle need to equal 180 degrees.
Let the exterior angle = X
You are told the interior angle = 38x +24
Now you have x + 38x +24 = 180
Combine like terms:
39x +24 = 180
Subtract 24 from each side:
39x = 156
Divide both sides by 39:
x = 156 / 39
x = 4
The number of sides is found by dividing 360 by the exterior angle:
360 / 4 = 90
There are 90 sides.
Answer: ∠MON = 15°
Step-by-step explanation:
∠LON = ∠LOM + ∠MON
(9x + 44) + (6x+3) = 77
9x + 6x + 44 + 3 = 77
15x + 47 = 77
15x = 30
x = 2
∠MON = 6(2) + 3 = 15
$369
Multiply 450, 8.2% and 10 to get $369
Answer:
2.6 : 400 -----convert both to either grams or kg, i'm doing grams
2600 : 400 ----simplify by 200
13:2 is lowest
True, but more through liquids.
