There is a 57% chance that both marbles will be red, and a 42% chance that the two marbles will be blue.
You know the angle sum of a square is 360 degrees.
So,
360=70+120+86+x
360=276+x
Then you solve for x by isolating it (minus 276 on both sides)
360-276=276-276+x
84=x
The last angle is 84 degrees.
Have a nice day:)
