The answer is C bc they just add the 0
Answer:
140
180 - 40 = 140
Step-by-step explanation:
Answer:
AROC=351 i believe
Step-by-step explanation:
substitute 3 for x in the equation and you get 730 and then substitute 1 for x and you get 28. subtact 28 from 730 and you get 702. then do "b-a" so 3-1 and you get 2. finally, divide 702 by 2 and you get 351.
<u>Given</u>:
Given that AC and BD are chords of the circle.
The two chords intersect at the point E which makes an angle 93°
The measure of arc BC is 161°
We need to determine the measure of arc AD.
<u>Measure of arc AD:</u>
The measure of arc AD can be determined using the property that "if two chords intersect in the interior of the circle, then the measure of each angle is half the sum of the arcs intercepted by the angles and its vertical angle".
Thus, applying the above theorem, we have;

Substituting the values, we have;



Thus, the measure of arc AD is 25°
