Question

me ayudaaaaaaaaannnnnnnnnnnnnnnn porfaaaaaaaaaa es trigonometrias si no saven no lo respondan por favor ayudaaaaaaaaaaaaaaaaaaaaaaaaaa :v

Answer 1

Explicación paso a paso:

3° sen(37°)=y/30

sen(37°)×30=y

y=18.05445

A)

4° sen(53°)=x/15

sen(53°)×15=x

x=11,97953

Cos(53°)=y/15

Cos(53°)×15=y

y=9.02723

x+y=21

E)

5° Cos(a°)=16/20

arcos(16/20)=a°

cos-1(16/20)=a°

a°=36,87

Cos(b°)=12/15

arcos(12/15)=b°

cos-1(12/15)=b°

b°=53,13°

D)
