Answer:
There are two different variables. X and Y.
Answer:
BC ≈ 14.7 m
Step-by-step explanation:
Using the Sine rule in Δ ABC
= 
To find ∠ A subtract the 2 given angles from 180°
∠ A = 180° - (90 + 28)° = 180° - 118° = 62°
Then
= 
( cross- multiply )
BC × sin28° = 7.8 × sin62° ( divide both sides by sin28° )
BC = 
≈ 14.7 m ( to 3 significant figures )
Answer:
1.5 bars of granola per student
Step-by-step explanation:
Number of students = 4
Number of granola bars = 6

= 1 1/2
= 1.5 bars of granola per student
Each student's share is 1.5 granola bars.
5x2(3x-1)+2(3x-1)factoring furhter gives(5x2+2)(3x-1)
-1.7×-6 is the answer. Hope this helps.
