Answer:
a = 4
Step-by-step explanation:
Since the triangle is right use the tangent ratio to find a, that is
tan30° = =
Multiply both sides by 12
12 × tan30° = a
12 × = a
Rationalise the denominator on the left side by multiplying the numerator/ denominator by
12 × = a ( cancel the 12 and 3 )
a = 4
