Answer:2
Step-by-step explanation:
2.5(2)
=5
It should always have the same perimeter if it stays the same geometric figure.
Let

be the identity matrix. Then pick whatever matrix you like for

.
Answer:
∠T = 135°
Step-by-step explanation:
Supplementary angles sum to 180°, thus
∠T + ∠S = 180
However, ∠T = 3∠S, hence
3∠S + ∠S = 180
4∠S = 180 ( divide both sides by 4 )
∠S = 45°, hence
∠T = 180° - 45° = 135°
