Answer:

78°

Step-by-step explanation:

angle CAW=180-168

angle CAW=12

angle DWB=12 vertically opposite to angle CAW

Sum of angles at a point=360

168+12+12+90+w=360

282+w=360

Collect like terms

w=360-282

w=78

Alicia is sewing a rectangle bedspread that measures 72 inches by 60 inches. The bedspread is red with a gold circle 18 inches i

Natalija [7]

Answer:

$4,066\ in^{2}$

Step-by-step explanation:

we know that

The area of the bedspread that is red is equal to the area of rectangle minus the area of the circle

step 1

Find the area of rectangle

The area is equal to

$A=72*60=4,320\ in^{2}$

step 2

Find the area of the circle

$A=\pi r^{2}$

we have

$r=18/2=9\ in$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute

$A=(3.14)(9)^{2}$

$A=254.34\ in^{2}$

step 3

Find the area of the bedspread that is red

Find the difference of the areas

$4,320\ in^{2}-254.34\ in^{2}=4,066\ in^{2}$

Which one of the following would prove that two triangles are congruenta

White raven [17]

Answer:

Corroponding side lengths are equal

Step-by-step explanation:

Two triangles may have the same areas, but the sides might be different or in different spots than each other. The same goes for perimeter, therefore it doesn't mean that they are congruent. If two triangles had the same angle measures, it could still have any size side lengths. When corrosponding side lengths are equal, they have the same angles as well, so they are only congruent in this example.

Hope this helps :)
