Answer:
Step-by-step explanation:
(b - c)/b * (b+c)/b Notice how the second fraction is inverted and multiplied. That's how you handle a 4 tier fraction. Here's a simpler example
What you get with your problem is
(b^2 - c^2)/b^2
3/10,3/5,0.4,1/2 I think is right but not sure
First piece is 5.2 cm...and second piece is 1.5 times as long
1.5(5.2) = 7.8 cm <== second piece
Okay, I think I understand.
Straight lines have a measure of 180°, so
52° + 59° + y = 180°
y = 69°
The measure of the inner angles of a polygon = (n - 2)180° where n is the number of sides. The shape is a triangle, so n = 3.
(3 - 2)180° = 63° + y + x
180° - 63° - (69°) = x
x = 48°
470,000 because when you round the number up, you get 470,000. it is reasonable
