Answer:
x >
Step-by-step explanation:
Add 3 and 1 to get 4.
Use the distributive property to multiply 5 by 9−x.
Subtract 45/5 from both sides.
Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.
Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.
Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.
Answer:
Step-by-step explanation:
the question is asking for the length of the side labeled x
use Pythagoras' theorem to find that side
where c = x because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem
c =
sooo plug in a = 14 and b = 10
c =
c =
c =
c= 17.20465..... ( that's the approx. length of side x in the problem )
since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA to remember how those functions fit on the triangle.
Sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...
Cos(Ф)=10/17.20465
Ф = arcCos(10/17.20465)
Ф = 54.4623° is the angle on the side with 10
the side with 14 then has an angle of 35.5376°
