Let ∠1, ∠2, and ∠3 have the following relationships. I WILL GIVE 20 POINTS PLS
∠1 and ∠2 are adjacent right angles.
∠1 and ∠3 are vertical angles.
What is the measure of ∠1 plus the measure of ∠3 minus the measure of ∠2?

If 1 and 2 are adjacent right angles, they are both 90º.

1 and 3 are vertical, which means they must be congruent, so 3 is also 90º

So: 90 + 90 - 90 = 90

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.
