B is the answer
Choice-a). two equal angles.
-- Choice-b).
-- Choice-c). If they were each 60°, then the total
for the triangle would be (130+60+60) = 250° .
-- Choice-d). two equal angles.
That symbol means that the number is squared.
So X^2 means that it's X squared.
The measure of angle BOC is 41 degrees
<h3>How to determine the measure of BOC?</h3>
The angles are given as:
<AOD = (5x - 4)° and BOC = (4x + 5)°
The angles are vertical angles.
So, we have:
(5x - 4)° = (4x + 5)°
Remove the bracket
5x- 4 = 4x + 5
Collect the like terms
5x - 4x = 4 +5
Evaluate the like terms
x = 9
Substitute x = 9 in BOC = (4x + 5)°
BOC = (4 * 9 + 5)°
Evaluate
BOC = 41°
Hence, the measure of angle BOC is 41 degrees
