Answer:C
Step-by-step explanation:
180-(60+40)=80°
C=80°
20/sin80. =a/sin40
a=(20sin40)÷sin80
=13.1
6s^2; where s is the side length
Answer:
585/3 = 195 students
Step-by-step explanation:Each group of three created (or used) 9 pictures, so that means three pictures per student.
Dividing 585 students by 3 pictures per student means that there are 585/3=195 students.
6f-1 and 2f+ 4f +2-3 are equal. 2f +4f+2-3 is 17 at f=3 because
(2•3)+(4•3)+(2-3) =
(6+12)+(-1) =
(18)+(-1)=
17
Plug in what f equals for f in the equation and evaluate
I hope this helps.
