Δabc is a right triangle. m ∠a is 6° less than three times m ∠b.
find m ∠a and m ∠b, assuming ∠a is an acute angle.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

x/3-10=8

x/3=18

x=48
