Question

You start driving east for 12 miles, turn left, and drive north for another 10 miles. At the end of driving, what is your straight line distance from your starting point? Round to the nearest tenth of a mile.

Answer 1

Answer:

17.2

Step-by-step explanation:

(14)2+(10)2=

 c2\,\,c^{2}c2

Use the Pythagorean Theorem.

196+100=196+100=196+100=

 c2\,\,c^{2}c2

Simplify.

296=296=296=

 c2\,\,c^{2}c2

Simplify.

±296=\pm\sqrt{296}=±296

​=

 c2\,\,\sqrt{c^{2}}c2

​

Square root both sides.

17.204650...=17.204650...=17.204650...=

 c\,\,cc

Simplify. Ignore negative root, as length must be positive.

17.2≈17.2\approx17.2≈

 c\,\,cc

Round to the nearest tenth.

Answer 2

Answer:

15.6=c

Step-by-step explanation:

(12)^2+(10)^2=c^2

144+100=c^2

244=c^2

square root of both sides=244= square root c^2

15.620499=c

15.6=c
