Step-by-step explanation:
Please specify values so we may answer. Judging by the looks of the question, this uses the concept of similarity
Y=15/x or xy=15 it seems that a should be 15/x
Answer:
Area of the triangle = 210 cm^2 .
Step-by-step explanation:
Perimeter of triangle = 4x + 1 + 3x - 1 + 3x = 70
10x = 70 - 1 + 1 = 70
x = 7.
Area A = 1/2 * base * height
= 1/2 * 3x * (3x - 1)
= 1/2 * 3(7) * (3(7) -1)
= 1/2 * 21 * 20
= 210.
Answer: in standerd form you need to solve 1 + 3 then 1 - 2

Answer:
Step-by-step explanation:
Of that list, only the square and the rectangle have the property you are asking for.
Try drawing it. The parallelogram has a shorter diagonal from the two obtuse angles than the diagonal from the two acute angles.
The rhombus has the same property as the parallelogram.
The kite has a far longer diagonal from the angle enclosed by the two long sides going to the angle enclosed by the two shorter sides, than a line going from the angle enclosed by one shorter and one longer side to the other angle made the same way.
