Answer:
I think x = 44°
Step-by-step explanation:
Finding the exterior angle:
180° - 45° = 135°
We know that x is multiplied by 3 (3x) so we divide 135 by 3.
135° / 3 = 45°
We know that we have to add 3° to the product of 3x, so we know the product of 3x will be less than 135°. The product should be 135° after 3° is added to it.
Trying a few possible answers:
43° × 3 = 129°
129° + 3° = 132°
That one wasn't quite right.
44° × 3 = 132°
132° + 3° = 135°

Answer:
x = 3
Step-by-step explanation:
Because you added 14 cards to your collection, we'll have to subtract that:
40 - 14 = 26
Knowing that 26 cards is half of your old card deck, we know that your old card deck is:
26*2 = 52
You have option b. 52 cards before.
