Question

2) Expresse em graus:

Answer 1

Explicação passo-a-passo:

a)

π ---------- 180°

5π/6 ------- x

xπ = 5π/6.180°

xπ = π150°

x = π150°/π

x = 150°

b)

π ----------- 180°

4π/3 -------- x

πx = 4π/3.180°

πx = π240°

x = π240°/π

x = 240°

c)

π ---------- 180°

3π/5 ------- x

πx = 3π/5.180°

πx = π108°

x = π108°/π

x = 108°

d)

π ------------ 180°

π/9 ----------- x

πx = π/9.180°

πx = π20°

x = π20°/π

x = 20°

e)

10π/9 = 10.180°/9 = 10.20° = 200°

f)

11π/18 = 11.180°/18 = 11.10° = 110°
