Answer:
B
Step-by-step explanation:
Angle ABD is congruent to angle CBD--->Definition of perpendicular lines
Segment DB is congruent to Segment Db--->Reflextive property of congruence
Angle ADB is congruent to angle CDB--->angle bisector theorem
2 angles and 1 side is congruent, therefore <em><u>the triangles are congruent by the ASA Congruence Theorem</u></em>
Kenetic friction but i know its kenetic cause of movement
1/3 x - 1/2 = 18 1/2
1/3 x = 19 (add 1/2 on the right side to 18 1/2)
x = 57 (multiply the reciprocal of 1/3 and that will be 3/1 or 3 to 19 to get x by itself)
So, the answer is x = 57 (d. 57)
