Right triangle has one degree = 45 so it's isosceles right triangle.
let y = hypotenuse of small isosceles right triangle

y^2 = 7^2 + 7^2
y^2 = 49 + 49
y^2 = 98

so
x^2 = 98 + 98
x^2 = 196
x = 98

answer
x = 98

Can you find the equation in standard form when given 3 or more orders pairs on a parabola

Anettt [7]

Answer:

Yes, you can

Step-by-step explanation:

The standard form of the equation of a parabola is $y=ax^2+bx+c$

When given three points, you substitute each point into the equation to obtain 3 simultaneous linear equations.

You then solve the three equations simultaneously to find the values of the constants a,b, and c.

You then substitute these constants into $y=ax^2+bx+c$
