Answer:
40 degrees!
Step-by-step explanation:
95 + 45 = 140
180 - 140 = 40
The lengths of sides of a triangle have to satisfy the triangle inequality, which states that the sum of the two shorter sides must exceed the length of the third side.
Here 9+8=17 (not greater), so these segments do not form a triangle.
What do you mean doubling? You can add 7+7+7 which equals 21.
8 over 20 equals 6 over 15
