Answer:
Area=576 cm²
Perimeter=123.4 cm
Step-by-step explanation:
We have to assume that ABCD would form a square and not a rectangle. If so, the area is simple: 24x24=576 (Just picture the half circle sliding into the empty space - it’s the same area.)
For the perimeter, we find it for the half circle first. 1/2(2)
(12)=37.7
Then add the top and bottom (24 and 24) to the left and right (37.7 And 37.7)
24+24+37.7+37.7=123.4

Answer:
<AED = 60
Step-by-step explanation:
Since triangle ADE is similar to triangle ABC
Angle ADE equals angle ADC
The angles of a triangle add to 180 degrees
<A + <ADE + <AED = 180
36 + 84+ <AED = 180
Combine like terms
120 + <AED = 180
Subtract 120 from each side
120-120 +<AED = 180-120
<AED = 60
1 because if you were to get h rn e measure of the problem right here it would be a cosine of 1
