Proof:-
In ∆XYZ and ∆VWZ

Hence
∆XYZ
∆VWZ(Side-Angle-Side)
When 2 triangle sides are known, the third side must be:
Greater than the Difference of the other 2 sides and
Less than the SUM of the other 2 sides
Difference = 5
Sum = 53
So, the sides that fit this requirement are 7 and 31.

SOLUTION:
For the marbles, 4 outcomes are possible.
For the cards, 2 outcomes are possible.
For the spinner, 2 outcomes are possible.
Thus, the total outcomes possible are;

Thus there are 16 possible outcomes.
The answer is bc cause you multiply 12 x 2= 24
