Answer:
The variables change
Step-by-step explanation:
Since we can't subtract c from -b we multiply both variables by a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac
the answer is 2.5 inches
≈ 68.2°
tan X= 20/8
tan X= 2.5
x= tan ⁻¹ 2.5
x ≈ 68.2°
696589
240 students
28/35=x/300
cross multiply to get 35x=300*28
divide both sides by 35 to get 240
