You have to put them into order, then multiple the two sides kf the triangle then put them together
2 (x - 5) = 8
To solve, you use the distributive property as shown below!! :)
2x - 10 = 8
2x = 18
x = 9
Hope this helped you :)
Answer:
you would distribute the 10 to the 2 so 20x + 80y - 60
Step-by-step explanation:
you distribute the 10 to each of the numbers
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.
Answer:
if I have my calculations right it would be £120
