Yep, b is correct
6/15=x/20
15x=6(20)
15x=120
15x/15=120/15
x=8
<u>Answer:</u>
x=65°
<u>Step-by-step explanation:</u>
Since all exterior angles add up to 360°.
⇒(3x+25°) + (20°) + (x+55°) =360°
⇒4x+100°=360° {Add up like terms}
⇒4x=260° {Subtract 100 from both sides}
∴ x=65° {Isolate x (divide both sides by 4)}
