The value of the base length x of the right angle triangle to the nearest tenth is 18.4.
What is the value of x?
From the diagram;
- Angle θ = 49°
- Hypotenuse = 28
- Base length x = ?
We use trigonometric ratio since its right angle triangle.
Cos = Adjacent / Hypotenuse
Cosθ = Base length / Hypotenuse
Cos( 49° ) = x / 28
x = Cos( 49° ) × 28
x = 0.656059 × 28
x = 18.4
Therefore, the value of the base length x of the right angle triangle to the nearest tenth is 18.4.
