Answer:

A. 9 mi.

Step-by-step explanation:

Here, use the Pythagorean Theorem, but leave "a" as it is.

a² + b² = c²

a² + 12² = 15²

a² + 144 = 225

a² = 225 - 144

a² = 81

a = √81

a = 9

The missing side is 9 miles long.

vesna_86 [32]
5% of £42 = £2.10
10% of £42 = £4.20
15% of £42 = £6.30

£42 - £6.30 = £35.70

£50 - £35.70 = £14.30

the answer is £14.30
