25 and 60 as the parallel lines means they have wth same gradient
Answer:
8.7 (nearest tenth)
Step-by-step explanation:
Applying pythagorean theorem, a² + b² = c²,
Where,
a = 5
b = the third side
c = hypotenuse = 10
Plug in the values
5² + b² = 10²
25 + b² = 100
Subtract 25 from each side
b² = 100 - 25
b² = 75
Take the square root of both sides
b = √75
b = 8.7 (nearest tenth)
