He worked 6.5 (6 and a half) hours . 40x + 65 would be the equation then you substitute 6.5 for x .
Answer:
The monument is approximately 86.6 feet tall
Step-by-step explanation:
The given monument parameters are;
The distance of the person from the monument = 50 feet
The angle of depression from the top of the monument to the person's feet = 64°
Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;
tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)
∴ The height of the monument = tan(Angle of depression) × The distance from the monument
Substituting the known values, gives;
The height of the monument = tan(60°) × 50 ≈ 86.6
The height of the monument ≈ 86.6 feet.

Applying the trapezium midsegment theorem, the length of XY is: 30.
<h3>What is the Trapezium Midsegment Theorem?</h3>
- Trapezium midsegment theorem states that the length of the median that joins two sides of a trapezium equals half the sum of he two bases of the trapezium.
Thus:
Let XY = x
WZ = 4/3(x)
DE = 35 (given)
Thus:
35 = 1/2(4/3x + x)
2(35) = 7x/3
70 = 7x/3
3(70) = 7x
210 = 7x
x = 30
x = XY = 30
Therefore, applying the trapezium midsegment theorem, the length of XY is: 30.
