Umm u are cute what is your number
<span>We know that OB bisects EC where they intersect would be at point O,
so the two lengths EO and OC must be equal.
2x - 20 = 70 - x
</span>[adding x + 20 to each side]
2x - 20 + x + 20 = 70 - x + x + 20
[simplifying]
<span>3x = 90
</span>[dividing each side by 3]
<span>
x = 30 would be the answer</span>
The answer is 2.5! Hope I helped!
