Q. If a tangent and a chord intersect at a point on the circle, and the lengths of the tangent and chord are 6 cm and 8 cm respectively, what is the angle between them?
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
90 degrees
Solution
The angle between a tangent and a chord at the point of contact is always 90 degrees.
Q. If a tangent and a chord intersect at a point on the circle, what is the relationship between the angle formed and the angle subtended by the chord at the center?
A.
They are equal
B.
They are supplementary
C.
They are complementary
D.
They are unrelated
Solution
The angle formed between the tangent and the chord is equal to the angle subtended by the chord at the center of the circle.
Q. If a tangent to a circle makes a 30-degree angle with a chord drawn to the point of tangency, what is the measure of the angle between the chord and the radius at the point of tangency?
A.
30 degrees
B.
60 degrees
C.
90 degrees
D.
120 degrees
Solution
The angle between the chord and the radius at the point of tangency is equal to the angle between the tangent and the chord, which is 30 degrees. Therefore, the angle between the chord and the radius is 90 - 30 = 60 degrees.
Q. If C invests $20,000 and D invests $30,000 in a partnership, and they agree to share profits in the ratio of their investments, what will be D's share if the total profit is $50,000?
