Answer:
9 inches^2
Step-by-step explanation:
Since a square has the same side lenghts the formula is
A=s*s
A=3*3
A=9
Well DAC is 180* so 180-70=110. DAB=110*.
To check 110+70=180* (aka : BAC+DAB=DAC)
Hoped I helped!
Answer:
28inches
Step-by-step explanation:
∠A + ∠B + ∠C = 180°
∠A + 65° +93° = 180°
∠A + 158° = 180°
∠A= 180°-158° = 22°
Using Law of Sines
a/sinA= b/sinB
a/sin22= 68 inches/sin65
a/sin22 = 68/0.9063 = 75.03
a = 75.03 x sin 22
a = 75.03 x 0.3746 = 28.106238≈28 inches
The answer would be 10. You would get it by multiplying 50 by 0.2. Hope I helped!
C=

so
18.84=2*3.14r
18.84=6.28r
r=3

A=3.14*9
A=28.26 or when rounded is 28
Hope that helps
