Step-by-step explanation:
Pathagory and Theorem
a^2+b^2=c^2
(x-3)^2+(x-4)^2=6^2
expand:
2x^2-14x+25=36
2x^2-14x-11=0
x=(\sqrt{71}+7)/2
perimeter=(x-3)+(x-4)+6=2x-1
insert the value for x into 2x-1
+6=perimeter
Hope that helps :)
6. the triangular portion is 14 because when finding the area of a triangle is b×h×1/2
54= 3*18
54= 3*3*6
54= 3*3*3*2
33=11*3
The only shared factor is 3.
Final answer: 3
M<ABX + m<CBX = 180
therefore, (14x + 70) + (20x + 8) = 180
Subtract 78 from both sides. Divide by 34.
x = 3
Plug in 3 for x.
m<ABX = 14(3) + 70 = 112
m<CBX =20(3) + 8 = 68
The correct answer is C.
A parallelogram has 2 pairs of opposite, equal, and parallel sides and a rectangle has 2 pairs of opposite, equal, and parallel sides BUT it also forms right angles between adjacent sides. In other words a rectangle is everything that a parallelogram is but with a little more, so the parallelogram would be inside of the rectangle. (if that makes any sense?)
