sin 23° = Opposite/Hypotenuse = b / c
0.39 = b / 30
b = 0.39 · 30
b = 11.722 cm
Area of a triangle:
A = 1/2 b h
A = 1/2 · 11.722 · 27.6
A  ≈ 161.7 cm²
Answer:
B ) 161.7 cm²

The area or the triangle is 161.7cm².

How to calculate the value?

From the information given, the following can be deduced:

sin 23° = opposite/hypotenuse

Let opposite = b

0.39 = b/30

b = 30 × 0.39 = 11.72

Area of triangle = 1/2 × b × h

= 1/2 × 11.72 × 27.6

= 161.7cm²
