Answer:
Question:14
3x4 (for the left square, 3 on the side(width) and 4 on the bottom(length))
3x9 (for the right square, 3 on the side(width) and 4 on the bottom(length))
3x13 (for the entire rectangle)
Question:15
3x10 (for the left, 3 on the side(width) and 10 on the bottom(length))
3x6 (for the right, 3 on the side(width) and 6 on the bottom(length))
Step-by-step explanation:
The correct answer is 2.5×10^2
Hope this helped :)
The formula for the total sum of the inner angles of the polygon is
Sn= (n-2) 180°
1) S6= (6-2) 180 = 4*180 = 720° In the hexagon all angles are equal
α= S6/6= 720/6= 120°
2) In each polygon the sum of the external angles is 360°
3) S5= (5-2) 180 = 540° than we can add up all angles
x+131+108+107+110=540 => x= 540-456= 84°
4) α = 360/5=72°
Good luck!!!
