Answer 1

Q7) 25.5

Q8) 25

Q9) 10

Q10) 12.7

Q11) 34

Q12) 24

Explanation:

Q7) c² = a² + b²

x² = 18² + 18²

x = √18² + 18²

x = 18√2 = 25.5

Q8) c² = a² + b²

x² = 20² + 15²

x = √20² + 15²

x = 25

Q9) c² = a² + b²

26² = 24² + x²

x = √26²-24²

x = 10

Q10) c² = a² + b²

x² = 9² + 9²

x = √9² - 9²

x = 9√2 = 12.7

Q11) c² = a² + b²

x² = 30² + 16²

x = √30² + 16²

x = 34

Q12) c² = a² + b²

25² = x² + 7²

x = √25² - 7²

x = 24
