Jenna is shopping for a new computer monitor. If she knows the measurements of the sides of the monitor, how can she figure out the diagonal measurement?
a^(2) + b^(2) = c^(2)
(a)_ + 14^(2) = c^(2)
121 + 14^2 = c^(2)
317 = c^(2)
c ~ 17.8 in.
The diagonal splits the rectangle into 2 right triangles.
Use the Pythagorean theorem.
