I’m not really sure of my answer
<u>Given</u>:
Given that a circle O with two tangents BA and BC.
The major arc AC is 234°
The minor arc AC is 126°
We need to determine the measure of ∠ABC
<u>Measure of ∠ABC:</u>
We know the property that, "if a tangent and a secant, two tangents or two secants intersect in the interior of the circle, then the measure of angle formed is one half the difference of the measures of the intercepted arcs."
Hence, applying the above property, we have;

Substituting the values, we get;



Thus, the measure of ∠ABC is 54°
Hence, Option b is the correct answer.

A is

absolute value is always positive, the minus sign vanishes (it literally means "how far away from zero" something is. distance can't be negative.)
B ist just 18
Answer:
140 cards
Step-by-step explanation:
-Let x be the total number of trading cards Lee has.
-Therefore, each person has:

#Kenny collects 50% more. We multiply his current amount by 1.5times:

#We are given that Kenny's new number is 220 more than Lee's x. We therefore equate and solve as below:

Hence, Lee had 140 cards
