The scores of eighth-grade students in a math test are normally distributed with a mean of 57.5 and a standard deviation of 6.5.

How do you use theorems about triangles to solve problems???

bazaltina [42]

9514 1404 393

Explanation:

Theorems about triangles identify relationships that can be used to formulate equations that can be used in the problem-solving process.

The idea with problem solving is to start with what you know, and make use of the relationships between that and what you don't know in order to find a solution.
