Angle measurement DEF=107 degrees
You must first find angle F- since it is against a flat line, we know 180=F+135. Subtract 135 from each side and we find F is 45 degrees.
Then, since a triangle’s angles must always equal 180 degrees, we subtract angles D and F from 180 to get 107 degrees.

Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inche
Vladimir [108]
Assuming that the sides of the box are square (having 90° angles on all four corners), then it should be relatively easy for us to find the length of the box, given the perimeter and the length of one side.
We know the length of all sides combined is 42 inches, and that the length of one side is 9 inches. With a rectangular prism, the length of one side is the same as the length of the opposite side, so there are two sides that measure 9 inches.
All we need to do to find the measure of both the other sides' lengths is subtract the known lengths from the total length.

9 + 9 = 18

42 - 18 = 24

So the rest of the side lengths added together is 24 inches.
There are two sides left, so all we have to do is divide by 2 to find the length of the box.

24 / 2 = 12

The length of Kate's jewelry box is 12 inches.
Hope that helped =)

A circle with center O is shown. Create the equation for the circle.​
gulaghasi [49]

Answer:

(5 - 1)^2 + (1 - 1)^2 = 4^2

Step-by-step explanation:

Circle equation: ( x - h )^2 + ( y - k )^2 = r^2

(h,K) is the coordinate of the center.

Center: (1,1)

(x,y) choose a point that could be the radius. (I choose the one on the top left side).

Point: (5,1)

Diameter: 8

Radius: 4

Plug in:

( x - h )^2 + ( y - k )^2 = r^2

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

Solve to see if it's true,

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

4^2 + 0^2 = 4^2

16 = 16 (This is true, therefore, the equation is correct).
