Answer:
x=sqrt30^2-25^2 b.) 16.58
Step-by-step explanation:
1. a = 10 b = ? c = 24
10² + b² = 24²
100 + b² = 576
b² = 476
b ≅ 21.8
2. a = 3 b = ? c = 5
b = 4 because of the 3 4 5 triangle rule
3. a = 9 b = ? c = 12
81 + b² = 144
b² = 63
b ≅ 7.9
Answer:
48
Step-by-step explanation:
times 4 times 3 times 4 + 48
$$ −\frac{7}{10} \div\frac{2}{5}= \frac{-7}{4} $$ . totally answer. I hope helping with this answer
