Help on my geometry please ! :(

Step-by-step explanation:

if the measures both the acute angles of a right angled triangle are equal ( 45° ), then the two smaller sides are equal.

so, x = 6

now, by pythagorus theorem :

=》

=》

( because x = 6 )

=》

=》

=》

=======================================================

Explanation:

The value of x = 6 since the two legs of a 45-45-90 triangle are always the same length. This triangle is isosceles.

The hypotenuse of any 45-45-90 triangle is exactly times larger compared to the leg length.

This means,

--------------

We can use the pythagorean theorem to confirm this

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
