Question

2x + 28 grade 24 minute 10 secunde = 180 grade
x = ?

Answer 1

2x+28.24.10=180
2x=179.59.60-28.24.10
2x=151.35.50

Answer 2

Explicație pas cu pas:

2x = 180° - 28°24'10"

2x = 179°59'60" - 28°24'10"

2x = 151°35'50"

2x = (150° + 1°) + (34' + 1') + 50"

2x = 150° + 60' + 34' + 60'' + 50"

2x = 150° + 94' + 110"

=> x = 75°47'55"
