Answer:
A = 3, B = 5.2
Step-by-step explanation:
i think that is right, i hope this helps.
Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram<span> bisect each other. Each </span>diagonal of a parallelogram separates it into two congruent triangles.<span> A square has got 4 sides of equal length and 4 right </span>angles<span> (right </span>angle<span> = 90 degrees). Since ALL the </span>angles<span> in a</span>quadrilateral add up<span> to 360 then 360 divided by 4 must be 90.</span>
3/1 is the slope of the line
My answer is 82. I added up 90 + 80 + 75 = 245. I then divided that by 3 because there are 3 different cultures. And the number was 81. something. So, I rounded and got 82. But I'm not sure if that's the right answer.
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft
Hope I helped :)
