Answer: -1(xy) exact value = -xy
rewrite -1(xy) as -(xy)
Step-by-step explanation:
Answer:
AD = 6.76 inches
Step-by-step explanation:
Taking the triangle ABC:
tan 45° = AB/BC
1 = AB/BC
AB = BC = 16 in
Taking the triangle DBC:
tan 30° = DB/BC
DB = BC * tan 30°
DB = 16 * tan 30°
DB = 9.24 in
Given that AD + DB = AB, then
AD = AB - DB
AD = 16 - 9.24 = 6.76 inches
50 tens = 50 x 10
50 x 10 = 500
your answer is 500
hope this helps
