Question

si:
ctg(3m-7)° × tg(5n-17°)=1 y m-n=30
calcula H = n/m​

Answer 1

Respuesta:

H= 8/5

Explicación paso a paso:

ctg(3m-7)° × tg(5n-17°)=1

(3m-7) = (5n-17)

3m - 5n = -10   (1)

m - n = 30    

m = 30 + n   (2)

(2) en (1)

3(30 + n ) - 5n = -10    

90 + 3n -5n = -10

90 - 2n = -10

100 = 2n

n = 50

en (2)

m= 30 + 50

m = 80

H= 80/50

H= 8/5
