Answer:
Step-by-step explanation:
AC = 50 cm
BC = 14 cm
Pythagorean theorem,
AB² + BC² = AC²
AB² + 14² = 50²
AB² + 196 = 2500
AB² = 2500 - 196
AB² = 2304
AB = √2304
AB = 48 cm
The miles previously covered by algae is 6 miles
let m represent the miles of the coastline covered by algae before the clean-up
fraction of miles covered after the clean-up =
x m = 
miles covered after the clean-up = 2 miles
= 2 miles
to determine the value of m, make m the subject of the formula.
To do this, take the following step :
multiply both sides of the equation by 2
m = 2 miles x 3
m = 6 miles
