The figure below shows ray and two lines that intersect at point F.Lines B-D and E-C intersect at F. The angle E-F-B divided into a right-angle and 35 degrees.What is the measure of ?A. 110°B. 125°C. 145°D. 160°
C. 145°
Explanation:
Since the angle E-F-B is divided into a right-angle and 35 degrees, we know that the angle E-F-B is 90 + 35 = 125 degrees.
Since the sum of angles around point F equals 360 degrees, we can find the measure of angle A as follows:
Angle A = 360 - 90 - 125 = 145 degrees.
Therefore, the measure of angle A is 145 degrees.
