9+4 = 13 total balls
1st pick would be 9/13 probability of picking yellow
2nd pick would be 4/13 probability
3rd pick would be 4/13 probability
total probability : 9/13 * 4/13 * 4/13 = 144/2197

Answer:
132cm ^ 2
Step-by-step explanation:
First solve the top rectangle, 4x7 = 28cm
then solve the bottom rectangle, 8x7 = 56cm
then solve the triangle, we know the entire bottom is 19cm, and 7 is subtracted, thereforth leavin 12, since there is 2 triangles its a base of 6, with a height of 8 making 48cm (and since there is 2 triangles no need to divide by 2)
28+56+48 = 132cm^2

Answer:
See below
Step-by-step explanation:
1 . Missing angle
Sum of interior angles in the triangle = 180°
- 180° - (105° + 29°) = 36°
2. Angle 1
- Angle 1 is exterior angle of the triangle
- Angle 1 = 55° + 78° = 133°
3. Angle 2
- Angle 2 = 180° - (55° = 78°) = 47°
4. The sum of exterior angle and adjacent interior angle equals 180°
If they are equal, then each will measure 180°/2 = 90°
So it is possible with the right triangle
