The answer would be 9. Because, you put 9 in each row adding up to 18 but it would still be a rectangle.
Hope this helps! :)
Answer:
6.02 i think
Step-by-step explanation:
The isosceles triangle has two sides congruent which mean they are equal. If two sides are equal, it also means that two angles are equal.
For triangle XYZ, we have angles shown below:
∠X + ∠Y + ∠Z = 180°
If ∠Y = a°, then we can have the expression for ∠X such as shown below:
∠X + a° + ∠Z =180°
∠X= 180° - a° - ∠Z
If ∠Z = ∠Y, then we have the final expression:
∠X = 180° -2a°
run towards it and throw stuff at it
