Question

What would n be? For question 1 don’t mind the bottom

Answer 1

n = 15

Explanation:

Using pythagoras theorem:

17² = n² + 8²

289 = n² + 64

n² = 225

n = 15

Answer 2

n = 15

Explanation:

Since this triangle is a right triangles (we know that from the little square in the corner, which denotes 90 degrees), we can use the Pythagorean Theorem.

The Pythagorean Theorem states that for a right triangle with legs a and b (these are the shorter two sides) and a hypotenuse c (the longest side), then the following holds true:
`a^2+b^2=c^2`.

Here, we can say that a = 8, b = n, and c = 17. So, plug these values in:

`8^2+n^2=17^2`

64 +
`n^2` = 289

`n^2` = 289 - 64 = 225

n =
`√(225) =15`

Thus, n = 15.

Hope this helps!
