Question

Hi there, hope everyone is well and staying cool :D

Answer 1

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 Δ$ABC = 17$

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
