Simple pythagorus theorem with the equation a^2=b^2+c^2
To find AC, (2^2)+(3^2)=4+9=13
AC=the square root of 13
Given that the triangles are similar.
When triangles are similar, all three pairs of corresponding sides are in the same ratio.
Similarly in the given triangles, the ratio of the corresponding sides are equal.
Cross multiplying, we get
Dividing both sides of the equation by -4.
So, we get
x = 7.

Step-by-step explanation:
Answer:
31.8%
Step-by-step explanation:There are 7 months that have 31 days so,
The odds the first selected month has 31 days is 7/12
The next month there are only 6 months left with 31 days of only 11 months to choose from
so the odds for the second are 6/11
To calculate the odds they BOTH have 31 months you multiply the two odds:
(7/12) x (6/11) = 42/132 = .318 so 31.8%
