Which two intergers is
between

options: -13 and -12 or - 11 and - 10 or and - 10 and -9 or -14 and -13.

​

So, the reason a triangle has an area of bh/2 is because it's half a rectangle. Draw a diagonal across a square and you have to right angles.

a2 + b2 = 1102

Hey, since it's a square, a and b are the same.

2a2 = 12,100

a2 = 6050

a = √6050 = 77.78 m

The area is given above, 6050 m2.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

the answer is 45 i just did it on oddesy ware
