Answer:
BC ≈ 4.0
Step-by-step explanation:
∠ DCA = 180° - 70° = 110° ( adjacent angles )
∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle
∠ DAC = 180° - 140° = 40°
Using the Sine rule in Δ ACD to find common side AC
= 
( cross- multiply )
AC × sin40° = 15 × sin30° ( divide both sides by sin40° )
AC = 
≈ 11.668
Using the cosine ratio in right triangle ABC
cos70° = 
= 
= 
( multiply both sides by 11.668 )
11.668 × cos70° = BC , then
BC ≈ 4.0 ( to the nearest tenth )
Answer:
3 gallons of orange juice
Answer:
65
Step-by-step explanation:
try 65 if not then 55
Answer: 110 degrees
Step-by-step explanation:
Rotations are rigid motions and thus preserve angle measure.
From stock A
The price increases as time passes till they both became constant eventually the price decreases as time passes
From stock B
The price is low in the beginning however as time passes it increases till it became constant
