Expand 

(4a + 12 = 12 + 4a)

Cancel 4a on both sides

12 = 12

Since both sides are equal there are infinitely many solutions

Process of elimination, cross out d) no solution. But I would best go with C)

icang [17]

Answer:

26°

Step-by-step explanation:

AC=tan 64

BC=x=sec 64

Using sine rule

(Sin 64)/tan 64 = (sin BAC)/sec 64

Cos 64 = (sin BAC)(cos 64)

Sin BAC= 1

BAC=90

ACB+ 64+90=180

ACB= 26°
