Answer:
All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle
Step-by-step explanation:
The derivative would be f'(x)= -9
Answer:
38.03 in
Step-by-step explanation:
Step 1: Calculate Craig's shoe length.
It's 4.112 in longer than Helen's shoe, which is 7.093 in. So, we simply add those two numbers to get 11.205.
Step 2: Add up all of the numbers
Now that we have everyone's shoe lengths, we just add them all up to get 38.03 in.
Hope this helps!
Let the supplement angle be x.
Supplement angles add up to 180:
x + x - 20 = 180
2x - 20 = 180
2x = 200
x = 100
Angle = 100 - 20 = 80
Answer: The angle is 80°
