Q. What is the measure of angle x if two parallel lines are cut by a transversal and angle x is an exterior angle that is supplementary to an interior angle measuring 120 degrees?
A.
60 degrees
B.
120 degrees
C.
90 degrees
D.
30 degrees
Solution
Exterior angles are supplementary to interior angles. Therefore, x = 180 - 120 = 60 degrees.
Q. What is the measure of each interior angle of a regular hexagon?
A.
120 degrees
B.
90 degrees
C.
60 degrees
D.
150 degrees
Solution
The measure of each interior angle of a regular hexagon is given by (n-2) × 180/n, where n is the number of sides. For a hexagon, n = 6, so each angle is (6-2) × 180/6 = 120 degrees.
Q. What is the measure of each interior angle of a regular pentagon?
A.
108 degrees
B.
120 degrees
C.
90 degrees
D.
135 degrees
Solution
The measure of each interior angle of a regular polygon can be calculated using the formula [(n-2) × 180] / n. For a pentagon (n=5), each angle = [(5-2) × 180] / 5 = 108 degrees.
Q. What is the measure of the angle subtended by an arc at the center of a circle compared to the angle subtended at any point on the remaining part of the circle?
A.
Half the angle at the center
B.
Equal to the angle at the center
C.
Twice the angle at the center
D.
None of the above
Solution
The angle subtended by an arc at the center of a circle is twice the angle subtended at any point on the remaining part of the circle.
Q. What is the measure of the central angle that subtends an arc of length 5 cm in a circle of radius 10 cm?
A.
30 degrees
B.
60 degrees
C.
90 degrees
D.
45 degrees
Solution
The formula for the arc length is L = rθ, where θ is in radians. Thus, θ = L/r = 5/10 = 0.5 radians. Converting to degrees, θ = 0.5 * (180/π) ≈ 28.65 degrees, which is closest to 30 degrees.
