Answer:
A=30cm, B=39cm
Step-by-step explanation:
They are an enlargement. Therefore, the sides are larger by the same proportion, otherwise, it wouldn't be an enlargement. Therefore, the bottom side of the big one is 3 times that of the small one. Therefore, the other sides are also 3 times, making A = 30cm and B = 39cm.

Answer:
10
Step-by-step explanation:
| | means absolute value. Absolute value is always positive, so your equation would be evaluated to 9 + 1 = 10
Answer:
m∠1 = 85°, m∠2 = 85°, m∠3 = 64°, m∠4 = 31°
Step-by-step explanation:
1. Since ∠3 and the angle labeled 64° are vertical, they are congruent, therefore m∠3 = 64°
2. By the same logic, since ∠4 and the angle labeled 31° are vertical, they are also congruent, meaning m∠4 = 31°
3. ∠4, ∠1, and 64° make up 180°, thus a straight line around them, so m∠1 + 31° + 64° = 180° --> m∠1 = 85°
4. ∠1 and ∠2 are vertical, so they are congruent, meaning m∠2 = 85°
Answer is. B. -65. It’s like adding with positive numbers but your doing it with negative
