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.
3. 8(3+8)
Explanation : 8x3 = 24 + 8x8 =64 which is congruent to 24 +64
Answer: 6
Step-by-step explanation:
Answer:
Hey there!
(8^2)^-4=8^2(-4), or 8^-8
8^-8 can be expressed as the third option.
