Hawick is 15 kilometers south of Abbotsford, and Kelso is 17 kilometers east of Abbotsford. What is the distance from Hawick to Kelso? Round your answer to the nearest tenth of a km.

Answer:

22.7 km

Step-by-step explanation:

The shape formed by this problem is a right triangle which is attached.

We apply Pythagoras Theorem

$x^2=17^2+15^2\\x^2=514\\x=22.7\: km$

The distance from Hawick to Kelso is 22.7 km (to the nearest tenth of a km)

at a point on the ground 15 ft from the tree, the distance to the top of the tree is 1 ft more than 2 times the height of the tr

muminat

Let's say the tree is of height h. The point 15 ft away, the base of the tree, and the height of the tree form a right triangle, where the length of the sides are h, 2h + 1, and 15 (see attached image).

Using the Pythagorean theorem, $h^2+ 15^2 = (2h +1)^2$

Simplifying it down, we get $3h^2+4h-224=0$

We can use the quadratic formula to solve this, where the solutions are $\frac{-4 \pm \sqrt{4^2 - 4 * 3 * (-224)} }{2*3} = \frac{-4 \pm \sqrt{2704} }{6} = \frac{-4 \pm 52}{6}$

Therefore the answers are $- \frac{56}{6}$ or $\frac{48}{6} =8$

The answer is 8 since the height of the tree must be positive.
