Answer:

x=25

Step-by-step explanation:

Hey There!

Those angles are supplements meaning all of them added together will equal 180

so we set up an equation

180 = 3x+2x+80 and solve for x

step 1 combine like terms

3x+2x=5x

now we have

180=5x+80

step 2 subtract 80 from each side

180-80=100

80-80 cancels out

now we have

5x=100

step 3

divide each side by 5

5/5 cancels out

100/5=25

x=25

Therefore the value of x is 25

Hope this helps :)
