The equation sin(40°) = can be used to determine the length of line segment AC. What is the length of ? Round to the nearest tenth

determining the length of line segment AC using sin(40)

Solution:

Given, the length of line segment AC = sin(40°).

Where Θ = 40°

AB = 20cm

We know that

sinθ = opposite/hypotenuse.

Substituting the values

sin(40°) = b/20

By further calculation

b = sin(40°) × 20

b = 0.64×20

So we get

b = 12.85cm

AC = 12.85 cm

Therefore, the length of AC is 12.85 cm

The equation sin(40°) = can be used to determine the length of line segment AC. What is the length of ? Round to the nearest tenth

Summary:

The length of line segment AC is 12.85cm
