Question 1 of 3
At point B, a straight line creates two adjacent angles. Angle ABC measures 70°. What is the measure of angle CBD?
Question 2 of 3
At point X two straight roads cross, forming four angles. Angle A measures 45°, the angle next to it on the same side of one road (angle B) measures 115°, and the angle opposite angle A (angle C) is also 45°. What is the measure of the remaining angle (angle D)?
Question 3 of 3
At a point four angles meet. Angle A is twice as large as angle B. Angle B measures 40°. Angle C measures 110°. What is the measure of angle D?
