Answer: The sum of the measures of the interior angles of a polygon is always 180(n-2) degrees, where n represents the number of sides of the polygon. The sum of the measures of the exterior angles of a polygon is always 360
Answer:
16cm by 5cm
Step-by-step explanation:
P=2(l+w)
A= wl
80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
you then would have to find 2 numbers that would add up to make 42.
When you try 16*2+5*2= 32+10= 42 cm as your perimeter.
16*5= 80 cm^2 as your area.
Answer: you would do -16 - 5 = -21
Answer:
D. 1800
Step-by-step explanation:
An overestimate is pretty self-explanatory, an amount bigger than what it's supposed to be.
Multiplying 22 * 68
1496
Rounding it will give you 1500, but the overestimate would be 1800. Because its a respected amount that is close to the answer of 22 * 68.
Answer:
Ans; Base=19.799cm
each of the other two sides=14cm
Step-by-step explanation:
two isosceles triangles are going to give you a square. So that means the area of the square will be 2(98cm^2) cos u added two of the triangles.There fore to get each side of the square, find the square root of the area of the square.you will get 14cm.that is equal to the length of the other two sides of the triangle. the base of the triangle is equal to the diagonals of the square(d=s√2).Use that to find the base of the triangle. Hope this helps.I am not good at explaining though
