Answer:
14
Step-by-step explanation:
you have to add 3 to the first of the two numbers. for example 5+3=8 so the answer would be 58, and because you're decreasing each number by 10 you would have to add 1+3=4 so tha answer must be 14.
You can solve this problem by using the pythagorean theorem.

Where the a- and b-values represent the sides of the triangle. Since the park is a sqaure, each side is equal. This means that both the a-value and the b-value are the same. Now, you must find the c-value.
145^2 + 145^2 = c^2
21,025 + 21,025 = c^2
42,050 = c^2 *now square root each side of the equation.*
205.06 = c
The length of the diagonal line is 205 meters.
