= 81° + a° + a° = 180° ( angle sum property )

81° + 3a = 180° \\ 3a = 180 - 81 \\ 3a = 99 \\ a =  \frac{99}{3} \\ a = 33°

The three angles of this triangle are :

\:  ∠1 \:= 81° \\ \:  \: ∠2 = 2a = 2 \times 33 = 66° \\ ∠3 = a = 33 \\  \\ ∴ \: a = 33° \:

Increase 14187.13 by 4.5%
Ksivusya [100]
If you increase a number by 4.5%, then you're adding 4.5% of that number to 100% of that number. So essentially you just multiply 14187.13 by 104.5%, or 1.045 to find the answer, which is 14,825.55.
