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:
6.7
Step-by-step explanation:
For this questions we have the oppsotie side and need the adjacent
out of SOH, CAH, TOA we will sue TOA
tan(56)=10/x
tan(56)/10=1/x
10/tan(56)=x
x=6.745 which rounds to 6.7
Answer:
4.2%
Step-by-step explanation:
percent error = (estimated value - actual value)/(actual value) × 100%
Here, the estimated value is 250 g, and the actual value is 250 g.
percent error = (estimated value - actual value)/(actual value) × 100%
percent error = (250 g - 240 g)/(240 g) × 100%
percent error = 10/240 × 100%
percent error = 0.041666... × 100%
percent error = 4.2%
5a.
18/9 = 12/x
18x = 12(9)...cross multiply
18x = 108
x=108/18
x=6
