Answer:
x=5
Step-by-step explanation:
Other than using the plain special aspect of a 45-45-90 triangle where the legs are x, x, and x√2, you can solve for this.
Since the two legs have equal length, they are both x. Using the pythagorean theorem:
(x^2)+(x^2)=50 (Because 5 squared is 25 and √2 squared is 2, multiplying them gives you 50).
You can add (x^2) and (x^2) because they are the same terms (x squared).
Simplifying like so gives you:
2x^2=50
Dividing by two on both sides:
x^2=25
Taking the square root of both sides:
x=5
original points (-2,0), (2,0), (0,2)
new points (-6.25,0),(6.25,0),(0,6.25)
the point (0,6.25) is the vertex that lies on y -axis
Answer:
Your answer would be: square the binomial, distribute 7 inside the parentheses, and then combine like terms
