Answer:
<u>We can conclude that Δ XYZ ≅ Δ RST by AAS postulate</u>
Step-by-step explanation:
Δ XYZ and Δ RST are congruents by AAS postulate because:
1. Their non-included sides YZ and ST are equal (10 units = 10 units).
2. Their angles ∠Y and ∠S are equal.
3. Their angles ∠X and ∠R are equal.
4.Their non-included sides XZ and RT are equal.
<u>Now, we can conclude that Δ XYZ ≅ Δ RST by AAS postulate.</u>

Step-by-step explanation:
Answer:
D. 30.96 in²
Step-by-step explanation:
The area of the shaded region = area of the the square - area of the circle
= (s²) - (πr²)
s = 12 in
r = radius of circle = ½ of 12 in = 6 in
π = 3.14
Plug in the values into the equation
Area of the shaded region = (12²) - (3.14*6²)
= 144 - 113.04
= 30.96 in²
