i) x²
ii) (x-10)²
b) (x-10)² = x² - 20x + 100
c) (30-10)² = 400 cm²
d) (x-10)² = 144 => x-10 = √144 => x = 12 + 10 = 22 cm
Answer:
13
Step-by-step explanation:
We can find the missing side length by using the pythagorean theorem
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
13 = c
So, 13 is the missing side length.
