Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

$3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}$

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

$x=3\sqrt{15}$ meters or 11.62 meters

= The value of the second car × (1 - losses percentage)^number of years

= £8,000 × (1 - 0.20)^5

= £8,000 × 0.80^5

= £8,000 × 0.32768

= £2,621.44

Hence, the value in the five years is £2,621.44

We simply applied the above formula so that the correct value could come
