Question

Considerando o triângulo retângulo, calcule a e b.

Answer 1

Olá Boa Tarde!!!!


a ------------------------- 12 v/3
seno (90) --------------- seno (60)

a . seno (60) = seno (90) 12 v/3
a . v/3/2 = 1 . 12 v/3
a = 12 . 2 v/3 /v/3
[ a = 24 ]

b -------------------------- 12 v/3
seno (30) --------------- seno (60)

b . seno (60) = seno (30) .12v/3
b . 0,866= 0,5 12
b = 2 . 0,5 12 / 0,866
b = 12/0,866
[ b = 13,85 ]
