the sum of all the angles in a hexagon is 720°, so:
(4x-5)+117+(3x-3)+(3x+6)+118+(4x-3)=720
4x+3x+3x+4x= 720+5-117+3-6-118+3
14x=490
x= 490/14
x= 35
Answer:
27
Explanation:
5 * 3 = 15 (5 triangles with 3 angles each)
3 * 4 = 12 (3 rectangles with 4 angles each)
15 + 12 = 27
1.62, 15/20, 16.2% is the answer
