Answer:
Area of the gray region = 64 square units
Step-by-step explanation:
Area of the white square = 64 square units
Length of a side of the given square =
=
= 8 units
By Pythagoras theorem,
Length of diagonal DB =
DB =
=
AD = DB = [Given]
OD = OC =
= 4√2
Therefore, AO = AD + OD = 8√2 + 4√2
= 12√2
Area of ΔACD = Area of ΔAOC - Area of ΔCOD
=
=
=
= 32
Therefore, area of gray part = Area of ΔACD + Area of ΔAED
= 32 + 32
= 64 square units

Answer:
a=100 b=50 c=30
Step-by-step explanation:
30+50+a= 180, A= 100.
90+40+b=180, B=50
A+B+C= 180
100+50+c=180, C=30
