Fill in the Blank Center - This is the center of the protractor. This point will lie on the of the
angle you are measuring or creating.

• Bottom Line - This will either be a solid line along the bottom of the protractor, or a broken line shown in the middle and on both sides of the center. This line will lie on top of the bottom
of the angle you are measuring or creating.

First Scale - This is the scale along the outside of the proctor. It is used to measure angles that open from the
and fan out in a clockwise motion.
.
Second Scale - This is the scale along the inside of the protractor. It is used to measure angles
that open from theand fan out in a counterclockwise motion.

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

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.
