Question

Dau 25 puncte!!! repede!!​

Answer 1

a) 2x=213°+37°=150°

x=150:2=75°

b)x=85°49-47°33`

x= 38°16`

c)3•(x-12°7`) + 41°=161°30'

3•(x-12°7`) = 161°30`-41°=120°30'

x-12°7' = 120°30:3=40°10'

x=40°10'+12°7'=52°17

d) 2x=213°-37°=176°

x=88

e)525°35`:x =5

5x=525°35

x= 105°7

f) x:8+15°40'=30°

x:8 = 30° => 29°60'

x:8 = 29°60'-15°40'

x:8 = 14°20

x= 14°20'•8

x= 112°160' => 114°40'
