What is the length of the hypotenuse for a right triangle with legs of length 9 and 40?​
Step2247 [10]

Answer:

c = 41

Step-by-step explanation:

{c}^{2}  =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {a}^{2} +  {b}^{2}  }

c =  \sqrt{ {9}^{2} +  {40}^{2}  }

c =  \sqrt{81 + 1600}

c =  \sqrt{1681}

c = 41

Need help use screenshot(SAT Prep) In △ABC, AB = BC = 20 and DE ≈ 9.28. Approximate BD. bd equals?
Lilit [14]

Answer:

5.36

Step-by-step explanation:

Given that:

<BAD = <CAE, therefore, BD = EC

Let's take x to be the length of BD = EC

BD + DE + EC = BC

BC = 20,

BD = EC = x

DE ≈ 9.28

Thus,

x + 9.28 + x = 20

x + x + 9.28 = 20

2x + 9.28 = 20

Subtract 9.28 from both sides

2x + 9.28 - 9.28 = 20 - 9.28

2x = 10.72

Divided both sides by 2 to solve for x

\frac{2x}{2} = \frac{10.72}{2}

x = \frac{10.72}{2}

x = 5.36

BD ≈ 5.36
