Answer:

x = 110

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + 40° + 30° = 180°

x + 70° = 180° ( subtract 70° from both sides )

x = 110°

x+40+30= 180°

x+ 70=180

x= 110°

While on vacation in Europe you notice that a tablet computer is selling for 600 euros in France and for 533 pounds in Britain.
serg [7]

The cost of the tablet computer is less in France. It is $8.

Step-by-step explanation:

Cost in France = 600 euros

75 euros = 1 dollar

600 euros = 600/75 dollars

=$ 8

Cost in Britain = 533 pounds

65 pounds = 1 dollar

533 pounds = 533/65 dollars

= $8.2

The cost of the tablet computer is less in France. It is $8.
