Question

expresa en grados los siguientes angulos
1.-3π rad
2. 4π rad

Answer 1

Recordemos que π Radianes equivalen a 180°

(-π/6)(180°/π) = [(180°-π)/(6π)] = -30°

0.8 Radianes

Tomo π ≈ 3.1416

(0.8 Rad)(180°/π) = [(0.8 Rad x 180°)/(π)] = 45.8365°

3π/4 Rad

(3π/4)(180°/π) = [(3π)(180°)/(4π)] = [(540π)/(4π)] = 135°

-3π Rad

(-3π)(180°/π) = [(-3π)(180°)/(π)] = -540°

4π Rad

(4π)(180°/π) = [(4π)(180°)/(π)] = 720°
