Answer:
Answer is D.
30
Step-by-step explanation:
all angles add up to 180(applys to triangles)
The points A,B,C,D make up the circumference of the circle
The measure of angle BAD is 65 degrees
<h3>How to determine the measure of angle BAD?</h3>
The measure of angle ODB is given as:
ODB = 25 degrees
Considering the triangle BOD, we have:
ODB + BOD + DBO = 180
Where:
ODB = DBO = 25
So, we have:
25 + BOD + 25 = 180
Solve for BOD
BOD = 130 degrees
The angle at an arc is twice the angle at the circumference.
So, we have:
BOD = 2 * BAD
Substitute 130 for BOD
130 = 2 * BAD
Divide both sides by 2
65 = BAD
Hence, the measure of angle BAD is 65 degrees

Answer:
12.5% of his time working.
Step-by-step explanation:
This is (85725 * 100)/( 141288+85725+81681+9945+1662+363447)
= 8572500 / 683748
= 12.5%.
