Question

I need help finding the side AB NOT THE ANGE AB which is 90°

Answer 1

Answer:

AB = 10.83 cm

Step-by-step explanation:

From ΔABC,

m∠B = 90°

By applying sine rule in the given triangle,

sinθ = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(37°) = $\frac{AB}{AC}$

AB = AC(sin37°)

AB = 18×(0.060182)

     = 10.833

     ≈ 10.83 cm

Therefore, AB = 10.83 cm is the answer.
