-7x5 -7x-u
-35+7u
(7 1/2) / (3/4) =
(15/2) / (3/4) =
15/2 * 4/3 =
30/3 =
10 <== there will be 10 three-fourth ft pieces
Answer:
Step-by-step explanation:
Using sine rule
SinA/a = SinB/b = SinC/c
A = 84° a = BC, C = 51°, c = 16
Sin84/BC = Sin51/16
Cross multiply
BC Sin51 = 16 × Sin84
BC = 15.91/Sin51
BC = 20.48unit
