Answer:
128.67 feet
Step-by-step explanation:
We would be solving this question using the Trigonometric function of tan.
Tan( of the angle of elevation) = height of the tower ÷ height of the shadow.
Angle of elevation = 65°
Height of the tower = unknown, which is designated as X
Height of the shadow = 60 feet.
Therefore,
tan 65° = X/ 60 feet
We crossmultiply
X = tan 65° × 60 feet
X = 128.67041523 feet.
Approximately, X = 128.67 feet.
Therefore, the tower is 128.67 feet tall.
Answer:
x < 5
Step-by-step explanation:
Solve the inequality by using the distributive property and inverse operations.
4(x + 5) > 10(x - 1)
4x + 20 > 10x - 10
20 > 10x - 4x - 10
20 > 6x - 10
20 + 10 > 6x
30 > 6x
5 > x
