<h2>Length of the other leg, expressed in radical form is
![4\sqrt{2}](https://tex.z-dn.net/?f=4%5Csqrt%7B2%7D)
</h2>
Step-by-step explanation:
We have Pythagoras theorem,
Hypotenuse² = Base² + Perpendicular²
Here we have
Hypotenuse = 9
Base = 7
Substituting
9² = 7² + Perpendicular²
Perpendicular² = 81 - 49
Perpendicular² = 32
![\texttt{Perpendicular = }\sqrt{32}\\\\\texttt{Perpendicular = }\sqrt{16\times 2}\\\\\texttt{Perpendicular = }4\sqrt{2}](https://tex.z-dn.net/?f=%5Ctexttt%7BPerpendicular%20%3D%20%7D%5Csqrt%7B32%7D%5C%5C%5C%5C%5Ctexttt%7BPerpendicular%20%3D%20%7D%5Csqrt%7B16%5Ctimes%202%7D%5C%5C%5C%5C%5Ctexttt%7BPerpendicular%20%3D%20%7D4%5Csqrt%7B2%7D)
Length of the other leg, expressed in radical form is
17 Is not the right answer whats the right answer
Answer: X = 7√2
Step-by-step explanation:
Let first Consider triangle BDC,
Cos C = adjacent/ hypothenus
Cos C = 7 / x ...... (1)
Also, let consider triangle ABC
Cos C = adjacent / hypothenus
Cos C = x / 14 ....... (2)
Since angle C is the same, equate equation 1 to 2
7/ x = x / 14
Cross multiply
X^2 = 98
Make x the subject of formula
X = sqrt (98)
X = sqrt ( 49 × 2 )
X = sqrt (49) × sqrt (2)
X = 7 sqrt(2)
X = 7√2
The probability of getting an even number is 1/2 and for getting a prime number, the probability is also 1/2
