Answer:
a = 6, b = 12, c = 6, d = 6√3
Step-by-step explanation:
The two triangles are the "special" triangles.
The 45-45-90 triangle has side lengths in the ratios 1 : 1 : √2.
The 30-60-90 triangle has side lengths in the ratios 1 : √3 : 2.
Then ...
c : a : 6√2 = 1 : 1 : √2 ⇒ c = a = 6
and ...
a : d : b = 1 : √3 : 2 ⇒ d = 6√3 and b = 12 . . . (since a=6)
The lengths are ...
a = 6, b = 12, c = 6, d = 6√3
Simple interest formulaInterest = PitwhereP=principal = $1000i=annual interest = 0.025t=time in years = 3
At the beginning of fourth year = at the end of 3 years
Interest = Pit = $1000*0.025*3 = 75
Balance in account after three years= $1000+75 = $1075
3 hours and also is there supposed to be a dollar sign before 2200
740% written as a decimal is 7.4 as a mixed number it would be 7 4/10 or simplified it would be 7 2/5
