Step-by-step explanation:
The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.
We have 2 right triangles. We can use the pythagorean theorem to solve for x.
a^2 + b^2 = c^2
x^2 + 20^2 = 25^2
x^2 + 400 = 625
- 400 - 400
x^2 = 225
x = 15
30 in each peanut treat, 25 in each coconut treat
Hope this helps :)
