Answer:
<h2>There are 5040 different possible sequences.</h2>
Step-by-step explanation:
Three identical notches and four identical bends are required in the sheet metal operation.
In total 7 things are required in the metal operation.
We can think it as we need to put the 3 notches and 4 bends in 7 places.
First, lets put the 3 notches in 3 places.
In order to do so, we need to choose 3 places from the 7 places.
We can choose 3 places in
ways.
The 3 notches can be arrange in 3! = 6 ways.
The 4 bends can arrange in 4! = 24 ways.
Thus, in total
different possible sequences.
Answer:
∠ L ≈ 21.6°
Step-by-step explanation:
Using the Sine rule in the triangle
=
, that is
=
( cross- multiply )
42 × sinL = 34 × sin27° ( divide both sides by 42 )
sinL =
, then
∠ L =
(
) ≈ 21.6° ( to the nearest tenth )
