Answer:
97.5 miles
Step-by-step explanation:
Multiply 65 by 1.5
It's an isosceles triangle 45° - 45° - 90°, therefore y = 5.
In that triangle, sides are in proportion 1 : 1 : √2.
Therefore we have x = 5√2.
<h3>Answer: B. x = 5√2, y = 5</h3>
Other method.
You can use the Pythagorean theorem:
x² = 5² + 5²
x² = 25 + 25
x² = 2 · 25
x = √(25 · 2)
x = √25 · √2
x = 5√2
<h3>Answer: B. x = 5√2, y = 5</h3>
