Answer:
Step-by-step explanation:
= (12-8)/12 × 100%
= 4/12 × 100%
= 100/3%
= 33.33%
x + y = 6
relationship: x = 6 -y or y = 6-x
so answer: c. y = 6 - x
show work:
x + y = 6
subtract x to both sides
x + y -x = 6 -x
simplify
y = 6-x
Answer:
The height of the tower is approximately 95.263 feet
Step-by-step explanation:
The given parameters are;
The distance from the foot of the tower where the angle of elevation is measured = 55 feet
The angle of elevation to the top of the tower from a point 55 feet from the foot of the tower, θ = 60°
Therefore, by trigonometric ratio, we have;

Therefore, we have;

The height of the tower = 55 feet × tan (60°) = 55 × √3 feet ≈ 95.263 feet.
Answer:
i = - 5
Step-by-step explanation:
Given
2i - 3 = 2(6 - i) + 7i ← distribute and simplify right side
2i - 3 = 12 - 2i + 7i
2i - 3 = 12 + 5i ( subtract 5i from both sides )
- 3i - 3 = 12 ( add 3 to both sides )
- 3i = 15 ( divide both sides by - 3 )
i = - 5
