Answer:
n = 35 inches
Step-by-step explanation:
Blue Triangle
Longer side = 91
Shortest side = 39
Brown triangle
Longer side = x
Shortest side = 15 in
When you have two triangles that are similar you have to set up your proportion like this
brown long/brown shorter = blue longer / blue shorter
x/ 15 = 91/39 Multiply both sides by 15
x = 91 * 15/ 39
x = 1365 /39
x = 35
I'm guessing the opposites are negative and positive so whenever you add two opposite numbers it will always be 0. The answer will always be 0.
For example:
-3 + 3 = 0
4 - 4 = 0
-15 + 15
measure it
Greg a tape measure and measure it
$20
49 is the outlier
