Answer:
29 cm
Step-by-step explanation:
The central triangle is isosceles, so the length if its right side (x) is the same as the length of its left side (29 cm).
x = 29 cm
Answer: Your answer for 13 people should be somewhere in the 20% range. Letting n=13 and we have about a 80.56% probability that no two out of the 13 share a birthday. As stated, the complement of this is the probability that at least two of the 13 share a birthday.

Answer:
![x^\frac{2}{3}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7B2%7D%7B3%7D)
Step-by-step explanation:
Using the power of power rule (multiply the exponents)
×
× ![^\frac{1}{3}](https://tex.z-dn.net/?f=%5E%5Cfrac%7B1%7D%7B3%7D)
![x^\frac{2}{9}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7B2%7D%7B9%7D)
When exponents are multiplied, add the answers:
x ^ ( 4/9 + 2/9 )
x ^ ( 6/9 )
x ^ ( 2/3 )
Answer:
Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.
Step-by-step explanation:
The Angle Addition Postulate is gotten from angles placed side by side to form a resulting angle that is the sum of all the individual angles.
If D is the interior of ABC then, ABC is split into two parts i.e ABD and DBC, then the measure of ABC is the sum of the individual two parts
m∠ABC = m∠ABD + m∠DBC.
Using the Angle Addition Postulate:
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 15 + 40 = 55°
m∠ABC = 55°
