Answer:
24 mm
Step-by-step explanation:
25^2 - 7^2
625 - 49
= 576
missing side = √576 = 24
Answer:
24 mm
Step-by-step explanation:
We use the Pythagorean theorem to solve this. In the theorem, a and b are the legs of the triangle and c is the hypotenuse:
a² + b² = c²
a² + 7² = 25²
a² + 49 = 625
Subtract 49 from each side:
a² + 49 - 49 = 625 - 49
a² = 576
Take the square root of each side:
√(a²) = √576
a = 24
