<span>0.75 (1/2x) = 60
60/3 is 20, which is 25% of her remaining money,
So her total remaining money is $80.
Then 80 x 2 = 160</span>
The size of the angle is always corresponding to the opposite side to it, for example
∠A corresponds to side BC
∠C corresponds to side AB
∠B corresponds to side AC
thus given x=6 then:
AC=x^2-x/2=33
AB=x^2+x/2=39
BC=x^2+x/3=34
thus the order of angles from the smallest to the largest is ∠B, ∠A, ∠C
I found 83.2285 I don’t know if your supposed to round it or not if so it’s 83
Hope I helped
