Answer:
i = h + 
Step-by-step explanation:
+ i = h
Taking
to the other side, you have:
i = h + 
I think its 2 cuz i think its 6^2
The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7
Sin30= opposite/hypotenuse
sin30= AC/10
AC= 4.5cm
Tan25= opposite/adjacent
Tan25= 4.5/ CD
CD= 10.7
