  • We know, sum of all angles of a triangle is 180°.
  • Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6

Sasha buys two ribbons of equal length. She cuts 9 pieces of the same length, L, from the first ribbon and finds that 5 inches a
nikitadnepr [17]

Answer:

50 inches.

Step-by-step explanation:

Let the length of the each ribbon was x.

Now, she cuts 9 pieces of same length L which means total length is 9L.

Now, doing the same she was left with 5 inches of ribbon. Hence, we have

[tex[9L+5=x.....(1)[/tex]

Similarly, we can write a equation for the second situation.

2L+40=x......(2)

From equation 1 and 2,

9L+5=2L+40\\\\7L=35\\\\L=5

Plugging this value in equation 1,

9(5)+5=x\\\\x=45+5\\x=50

Therefore, the length of each ribbon when she bought them was 50 inches.
