Hi there, hope everyone is well and staying cool :D
gogolik [260]

Answer:

A) By using the Pythagorean Theorem, we will see that 8^2 + 15^2 = 17^2. If we simplify it, we will find that the hypotenuse of ΔABC = 17

B) approximately 18.79

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is  leg^2 + leg^2 = hypotenuse^2

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, 8^2 + 17^2 = AD.  

  • 8^2 + 17^2 = 64 +289
  • 64 + 289 = 385
  • \sqrt{385} \\ ≈ 18.79

Hope you do well on the rest of your math problems :D
