Notice the larger triangle is a right-triangle, and the small one is also a right-triangle. Also notice the "angle tickmark" on each. So both angles have a pair of angles that are equal on each.
the triangles are similar by AA.
5x-y
=5(3)-1
=15-1
=14
Therefore, the answer is 14.
Answer:
is the size of the square
Step-by-step explanation:
Let the side of the square cut from the cardboard be “x”
Size of the square base =
, height of the box = x
Volume of square box = Area * height =
Differentiating the above equation and equating it to zero, we get –
d/dx
d/dx
= d/dx
d/dx
On solving above equation, we get –
The difference of the area of the two right triangles is 33.0 cm^2.
