Find the value of x.
a) x = 86.
b) x = 102
c) x = 13
d) x = 43

Answer 1

d) x=43

Explanation:

A rule for this problem can be as followed:

All exterior angles of a quadrilateral sum up to 360 degrees.

So, let's write an equation:

3x+2x+(x+2)+100=360

subtract 100 from both sides

3x+2x+(x+2)=260

combine like terms

6x+2=260

subtract 2 from both sides

6x=258

divide both sides by 6

x=43

So, d is the correct option.

Hope this helps! :)
