Answer:
x = 20 cm
Step-by-step explanation:
The triangles given are similar triangles because they share the same angles. Because they are similar, their side lengths are in the same ratio, or proportion to one another. The left side of the larger triangle has a length of 121cm + 11cm = 132cm where the smaller triangle only has a length of 11 cm. We can put these lengths into a ratio:
Since the other side of the triangle would have to be in the same proportion, or ratio, we can set up the following proportion:
Use cross-multiplication: 5x + 20 = (10)(12) or 5x + 20 = 120
Subtract 20 from each side: 5x + 20 - 20 = 120 - 20 or 5x = 100
Divide and solve for 'x': 5x/5 = 100/5 or x = 20 cm
Answer:Numbers are divisible by 3 if the sum of all the individual digits is evenly divisible by 3. For example, the sum of the digits for the number 3627 is 18, which is evenly divisible by 3 so the number 3627 is evenly divisible by 3.

Step-by-step explanation: i took it
I followed the numbers across, thinking to myself "this won't be
too hard to multiply, because they're all small numbers". And then
when I got to the zero, I burst out laughing ! It doesn't matter at all
what all the other numbers are. Once there's a zero in there, the whole
product will be <em>zero</em>, no matter what else gets multiplied along the way.
There could be millions and billions in there. You wouldn't need to do
any calculating at all. With zero as a factor, you know right away that
the product is zero.
