Answer:

π/90 or 0.0035 units

Step-by-step explanation:

equation: <em>length of the arc = ∠of the angle/360 * circumference</em>

Substitute: <em>S = 0.4/360 * 10π</em> --> C = 2πr

Simplify: S = 1/900 * 10π

Simplify: S = π/90 ≈ 0.003489 units

The interior angles of a triangle have measures (2x - 5), (4– 1), and 30°
const2013 [10]

Answer: x=26

Step-by-step explanation:

1. Write the equation 2x-5+4x-1+30=180 because all triangle angles add up to 180°

2. Simplify the equation by combining like terms. Write the equation as 6x+24=180

3. Subtract 24 from both sides. Write the equation as 6x=156.

4. Divide 156/6 and get 26. That is your answer (x=26).
