In this question, you need to use Pythagoras' Theorem, c^2 - b^2 = a^2. In this case, C is 14 and B is 6, so you would do 14^2 - 6^2 = 196 - 36 = 160, and the approximate square root of 160 is 12.6 inches, which is your answer.

I hope this helps!

Answer:

12.6 inches

Step-by-step explanation:

We only need to apply Pythagoras theorem to solve this problem.

Pythagoras theorem state that in a right-angle triangle,

opposite² + adjacent²  = hypotenuse²

From the question hypotenuse = 14 inches

one of the leg, lets say adjacent = 6 inches

Let x be the length of the other leg.

We can now proceed to insert our values into the formula;

opposite² + adjacent²  = hypotenuse²

         x²    +      6²           = 14²

         x²   +   36   = 196

Subtract 36 from both-side of the equation

x²   +  36  - 36   = 196 -  36

x²   =  160

Take the square root of both-side to get the value of x

√x²   =  √160

x = 12.649

x≈12.6

Therefore the approximate length of the other leg is 12.6 inches

Help me find the answer <br>Tan 0 and Cot O ​
vesna_86 [32]

Answer:

Step-by-step explanation:

we can say the angle is also +45° going in the clock wise direction.  so take Tan(45)= 1

Cot(45) = 1

b/c  Tan(45) = Sin(45) /Cos(45) = (\sqrt{2}/2) / (\sqrt{2}/2)   ofc that's just 1

b/c Cot(45) = Cos(45) / Sin(45) , which is the same as above 1
