Answer:
x=2
Step-by-step explanation:
Expand 5(x-1)+3: 5x-2
5x-2=7x-6
<em>add 2 both sides and simplify</em>
5x=7x-4
<em>subtract 7x from both sides</em>
5x=7x-4-7
___-7____
<em>simplify -2x=4x divide both sides</em> by 2, -2x/-2=-4/-2
x=2
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.
