Answer 2

Step-by-step explanation:

Tan theta = 1/√3

theta = π/6 = 30°

30 +90 +x = 180°....(triangle)

x= 60° = C

1)

SinA Cos C + Cos A SinC

above equation is just a formula of

Sin(A+C)

Sin(30+60)

Sin(90)

= 1

2)

Cos A cos C - Sin A SinC

above equation is also just a formula

Cos (A+C)

Cos (30 +60)

Cos (90)

= 0
