Answer:

x = 40

Explanation:

Hello there!

Remember the circumference of a circle in degrees is equal to 360

so all of the arcs added together will equal 360

360 = x + 20 + 3x + 15 + 4x + 5

step 1 combine like terms

1x+3x+4x=8x

20+15+5=40

now we have 360 = 8x + 40

step 2 subtract 40 from each side

360 - 40 = 320

40 - 40 cancels out

now we have 320 = 8x

step 3 divide each side by 8

320/8=40

8x/8=x

we're left with x = 40
