Answer:
This is a 45-45-90 right triangle
So we know that because at least one angle is 45 degrees and there is a right angle.
A 45-45-90 triangle has congruent (equal) legs {x} and the hypotnuse is
x√2
So using that information we know X = Y
Since they are both legs and legs are congruent in this case.
The hypotnuse is laid out for us which is 8.
We can make an equation.
Since the hypotnuse would be x√2
x√2 = 8
Now we solve.
You’d get 5.6528… or √32
X and Y both equal √32

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 4
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 4 = -x + 5
- Add <em>x</em> to both sides: 3x - 4 = 5
- Add 4 to both sides: 3x = 9
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -x + 5
- Substitute in <em>x</em>: y = -3 + 5
- Add: y = 2
Answer:
-61/4
Step-by-step explanation:
-1/2 + x = - 21/4 - 23/4 - 19/4
-1/2 + x = -(21+23+19)/4
x = -63/4 + 1/2
x= -63/4 + 2/4
x = -61/4
