Answer:
Step-by-step explanation:
Triangle A
Use Pythagorean theorem.
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25
x = √25
x = 5 cm
Triangle B:
y² = 12² + 5²
= 144+ 25
= 169
y = √169
y = 13
Two integers are 26 and 28
Step-by-step explanation:
- Step 1: Let the two consecutive positive integers be x and x + 2. Product = 728
x(x + 2) = 728
x² + 2x - 728 = 0
x = -2 ±√4 - 4 × 1 × -728/2 (using quadratic formula)
= -2 ±√4 + 2912/2
= -2 ±√2916/2 = -2 ± 54/2
= -56/2, 52/2
= -28, 26 (negative value is neglected)
∴ x = 26
x + 2 = 28
