Question

What is the value of X in degrees?

Answer 1

48 degrees

right on edge

Explanation:

With a triangle that has angles 47 degrees 85 degrees and angle x the equation would be 47 + 85 + x = 180 because a triangles angles always add up to 180, the number needed would be 48 degrees

Answer 2

X is a variable so it can replace any number

Example:

x=4

x*3+1=y

if x is 4 then you can plug in

(4)*3+1=y

12+1=y

13=y

That is how variables like (x) are used :)
