Answer:

Step-by-step explanation:
Since the smaller triangles have a side of the same length, they share one side, and the included angle is 90°, the triangles are congruent.
This means the length of the side to the left is also x as shown in the image below.
The bigger triangle is also right and has side lengths of x, x, and 6 (the hypotenuse), thus:

Operating:


Since 18=9*2


The options are not clear enough, so I cannot make a choice.
Answer:
32
Step-by-step explanation:
Because if you put the lack of other side to the other side, it will complete.
One roll = 4
eight rolls = 4 × 8 = 32
91m+13n+52 ....
hope this helps!!!

Answer:
x ≈ 14.87
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 10² + 11² = 100 + 121 = 221 ( take the square root of both sides )
x =
≈ 14.87 ( to the nearest hundredth )
