The complete question found on brainly (ID: 14303570 ) is stated below:
Find the length of side BC.
Give your answer to 1 decimal place.
∠A = 58°
AC = 14cm
Find attached the diagram of the triangle.
Step-by-step explanation:
From the diagram
∠A = 58°
∠B = 90°
AC = 14cm
The triangle is a right angled triangle
To get the length side of BC, we would
apply trigonometry SOHCAHTOA.
In this question the sine ratio would be appropriate since we know the hypotenuse but we are looking for the opposite side (BC).
Sine ratio: Sin58° = opposite/hypotenuse
Sin58° = BC/AC
Sin58° = BC/14
BC = 14sin58°
BC = 14 × 0.8480
BC = 11.9cm
length of side BC = 11.9cm (1 decimal place)
