G^-1(x)=x/2-3/2. Let me know if I was correct
Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.
We convert the given information to equations, step by step.
Point 1: When Jackie is 1 mile farther from the intersection than Judy.
This means y is 1 mile more than x.
So,
y = 1 + x
Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection.
Distance between is x+ y.
So, x+y is 2 miles more than y.
x+y = y + 2
⇒
x = 2
From point 1 we have:
y = 1 + x = 1+ 2 = 3
So,
Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.
Answer: <em>∠1 = 37.5°; ∠2 = 37.5°; ∠3 = 133°.</em>
Step-by-step explanation:
<em>∠1 = ∠2 = (180° - 105°) ÷ 2 = 37.5°</em>
<em>∠3 = 180° - 23° - 24° = 133°</em>
True, and it's called an isosceles right triangle :D
