Answer:
c
Step-by-step explanation:
When we know two sides and the included angle, there is a formula we can use.
We know angle C = 35º, and sides a = 20cm and b = 19.5cm.
using the formula
Area =(½)ab sin C(angle)
Put in the values we know:
(20×19.5÷2)×sin(35)=
111.8474050885 cm^2
rounded = 111.85 cm^2
answer is c
No, it is not because IDENTITY means itself, so the answer has to be the same.
-5—->-29
-1—->-5
0—->1
1—->7
55% of x is 70
0.55 times x=70
divide both sides by 0.55
127.27272727
round
127.3
