Answer:
12
Step-by-step explanation:
use Pythagorean theorem
37^2 = 35^2 + x^2
x= ±![\sqrt[2]{37^2-35^2}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B37%5E2-35%5E2%7D)
x1 = 12
x2= -12 but it is illogical as length cannot be negative
answer: x = 12
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

Answer:
x = 20
Step-by-step explanation:
(2 + 3x) and 62° are vertically opposite angles and are congruent, so
3x + 2 = 62 ( subtract 2 from both sides )
3x = 60 ( divide both sides by 3 )
x = 20
