Answer:

AB = 90 degrees

AC = 60 degrees

Step-by-step explanation:

Since every triangles angles equal to 180 you first subtract 30 from 180 which is 150 degrees. You can see there is a square around a vertex which means that angle is 90 degrees. Now subtract 90 from 150 which is 60 degrees. So the last angle is 60 degrees.

BlackZzzverrR [31]

Answer:

5/14

Step-by-step explanation:

We take away a blue card

The total number of cards is 7

There are 4 blue cards

P(2nd card is blue) = blue/total = 4/7

The probability of blue blue is P(blue blue ) =

P(1st card is blue)*P(2nd card is blue) =

5/8* 4/7

20/56

We can divide the top and bottom by 4
