The side view of a house (the “side elevation”) is often in the shape of a pentagon. If the angle at the roof is 150° and there are two other
angles of 90°, what is the sum of the measures of the other two
angles?
I need it fast.

is there any photos or whatever?

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.

what is the model?

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
