It is c.
explanation:
20+130+h =180
when you solve you get h=50
130+g = 180
g= 50
50+60+f = 180
f=70
18:20
Multiply each side by 2
The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.
For a 30-gon, the sum of interior angles is (28) x (180) = <u>5,040 degrees</u>.
It makes no difference whether or not the polygon is convex at every vertex.
Answer:
R760
Step-by-step explanation:
If $1 is equivalent to R8 and the total oil costs $95 you must multiply 8x95. This leaves you with an answer of R760
