Step-by-step explanation:
Polygons (shapes made of straight lines) where no angle is greater than 180 degrees. If even one angle is greater than 180 then it is a concave polygon.
The greatest common factor of 10 and 40 is 10.
It is 1/3x wide
add the terms, the answer is 1/3x
45,42,126
multiply by 3
m9 = 115
m4 =110
m10=65
m11= 70
m8= 70
m5 = 65
m3 = 70
m14 = 115
12.5
30-60-90 triangles always have the height be sqrt3 the base.
