Answer:
55 degrees
Step-by-step explanation:
a line is 180 degrees. also, all angles in any triangle add up to 180 degrees. so, find the missing angle in the triangle by 180-30-25=125 degrees. Then to find angle 4, 180-125=55 degrees.
The quantity n written to the left is called the index.
Radicals - The symbol n√x. used to indicate a root is called a radical and is therefore read "x radical n," or "the nth root of x." In the radical symbol, the horizontal line is called the vinculum, the quantity under the vinculum is called the radicand, and the quantity n written to the left is called the index.

Answer:
24 final sums, different sums are 16, 18, 20, 22 or 24.
Step-by-step explanation:
First, count how many different orders of 1, 2, 3 and 4 are possible. The first number can be chosen in 4 different ways (it can be any of 4 numbers), the second - in 3 different ways (it can be any of remaining 3 numbers), the third - in 2 different ways (any of remaining 2 numbers) and the last number - in 1 way (only one number left). In total,
different orders.
For each order we can
- write 3 sums in the first step;
- write 2 sums in the second step;
- write 1 sum in the last step.
In total, 6 sums (only 1 of them is final). So, there are 24 final sums.
Different final sums are 16, 18, 20, 22 and 24.
