Answer:
For #1, 8.9.
Step-by-step explanation:
I can attempt to answer it, but I can't promise anything.
Alright, so, the equation for this should be A²+B²=C²
C is usually the longer side, which for you is the side that is missing.
Let's try the first one. If what I see is right, the 2 sides are 4 and 8. A is 8 and B is 4.
That means that the equation would be 8²+4²=C²
That would be 64+16=80
The equation is now 80= c²
The opposite of "to the power of 2" is a square root. So, now you're going to find the square root of 80, which is 8.9 to the nearest tenth.
So, for the first question, the answer should be 8.9
I hope this helps you solve the rest.

Answer:
x = 13
Step-by-step explanation:
→ Remember the amount of degrees a triangle sums to
180°
→ Make an equation
8x - 44 + 8x - 44 + 8x - 44 = 180
→ Simplify
24x - 132 = 180
→ Add 132 to both sides
24x = 312
→ Divide both sides by 24
x = 13

Step-by-step explanation:
A matrix is an algorithm that has many applications. It is composed of a series of numbers (typically coefficients of variables) organized in a pattern. When dealing with a matrix, one must always remember the rule (rows by columns). One such application is that a matrix can facilitate the process by which one solves a system of equations.
When given the following system:
y = 5
4x = 3
One can see that not all of the equations have all variables in them. Yet, bear in mind that any number times zero is zero, therefore, one can rewrite the equation such that it has all of the variables if one ensures that the coefficient of the missing variable is (0).
y + 0x = 5
0y + 4x = 3
Now organize this in the form of a matrix, the coefficients of the variable go in a (4 x 4) since there are now (4) elements. The variables are vertically arranged in a (2 x 1), and the equation results are also vertically arranged in a (2 x 1).
