Question

Ｄｅｔｅｒｍｉｎｅ　ｏ　ｖａｌｏｒ　ｄｅ　(ａ)

２ａ／３　＋　３０°　＝　３ａ／４＋　２７°

Answer 1

$\frac{2a}{3 } + {30}^{o} = \frac{3a}{4} + {27}^{o} \\ \frac{2a}{3} - \frac{3a}{4} = {27}^{o} - {30}^{o} \\ \frac{8a - 9a}{12} = - {3}^{o} \\ \frac{ -a}{12} = - {3}^{o} \\ - a = - {36}^{o} \\ a = {36}^{o}$
Espero que tenha entendido!!
