Question

Me ajuda com os valores de X e de Y

Answer 1

See whether you agree with the following statements based upon the diagram:

Vea si está de acuerdo con las siguientes declaraciones basadas en el diagrama:
100 + y
tan 60 = x / y and tan 30 = -------------
sqrt(3)

100 + y
Then x = sqrt(3)*y and x = -------------
sqrt(3)
100 + y
From these 2 equations we see that sqrt(3)*y = --------------
sqrt(3)

100 + y
From these 2 equations we see that sqrt(3)*y = --------------
De estas 2 ecuaciones vemos que sqrt(3)

Then 3y = 100 + y, so that 2y = 100 and y = 50 degrees (answer)

x x
Again, tan 60 deg = ------- => sqrt(3) = --------------- y 50

Then 50 sqrt(3) = x (answer)
