Answer:
Step-by-step explanation:
given tanB= 4/3
so sinB=4/5
n cosB=3/5
given BC=15
BA=BC*cosB
=15*3/5
=9
AC=BC*sinA
=15*4/5
=12
Triangle ABC and DBE are similar by AAA
DB= BA-AD
=9-3
=6
DB/BA=DE/AC
6/9=DE/12
DE=12*6/9
=8
(a) 1, 2, 7, 14 (b) 1, 3, 9, 27 (c) 1, 2, 3, 6 (d) 1, 3, 5, 15 ... 4.4 Sine, Cosine and Tangent. 1. (a) hyp : BC ; adj : AC ; opp : AB. (b) hyp : DF ; adj : DE ; opp : EF. (c).
SO THE ANSWER IS 8
maybe 18
Numbers greater than or equal to 0.
The domain of this function is {x∈R | x≥0}, meaning that x can be anything greater than or equal to 0.
did it
450 divided by 75 = t
he plated 6 trees
70 hours.
you need to subtract 450 from 75 which tells you you need 350 more dollars then you need to do 5x70 which gives you 350.
