The area of polygon D is given by:
Ad = k ^ 2 * Ac
Where,
k: scale factor
Ac: area of polygon C
Substituting the values we have:
Ad = (1/2) ^ 2 * (40)
Ad = (1/4) * (40)
Ad = 10 square units
Answer:
the area of Polygon D is:
Ad = 10 square units
Answer: (i) SPQ = 
(ii) SQR = 146°
Step-by-step explanation:
<SPQ = 146 - 68 = ( the exterior angle of a triangle is equal to the sum of the two opposite interior angle )
RQS is the exterior angle
The opposite interior angles are PSQ and SPQ , from the theorem :
PSQ + SPQ = RQS , that is
68 + SPQ = 146
SPQ = 146 - 68
SPQ =
(ii) SQR = RQS
Therefore : SQR = 146°
Answer:
10.6 inches squared
Step-by-step explanation:
P = 2(L + W)
P = 2( 1.4 + 3.9)
P = 2 x 5.3
P = 10.6 inches squared
V = 4/3 r^3 hope this helps I’m not sure if it’s right
