The answer is D. All you have to do is add all of the angles for each choice you're given. It has to add up to exactly 180, because every triangle is 180 degrees.
(2x100) (3x10) (2x1) / (4x1)
Answer:
12/13
Step-by-step explanation:
There are 52 cards in the deck
4 are aces
That leaves 52-4 or 48 that are not aces
P(not an aces) = cards that are not aces / total
= 48/52
=12/13

Step 1 : subtract 1 from both sides

Step 2 : Divide both sides by 3


Step 3 : Find the square root of 9

x= (-3,3)
remember negative × negative = positive
