<span>Letisha will have earned however much money she began with plus 1.5 percent. This can be found by taking the initial principal on January 1 of the previous year, multiplying it by 0.015, and adding the result to the previous balance to get the end-of-year total.</span>
Bu using Pythagoras theorem
(x^2)+(21)^2=(75)^2
Therefore. 5625-441=(x)^2
X^2=5184
Therefore x=72
Third side length=72 units
95% = 0.95
280 - (280 * 0.95)
