Answer:

y = \frac{96}{5}

Step-by-step explanation:

given that y and x are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

to find k use the given condition y = 12 when x = 5

k = \frac{y}{x} = \frac{12}{5}

y = \frac{12}{5} x ← equation of proportionality

when x = 8, then

y = \frac{12}{5} × 8 = \frac{96}{5}

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find t
Juliette [100K]

Answer:

26.3 m

Step-by-step explanation:

The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 37 m. Find the height of the building.

We solve the above question using Pythagoras theorem

c² = a² + b²

Where

c = Longest part of the triangle = 37 m

a = Height of the triangle = ?

b = Length of the shadow = 26 m

Hence:

37² = a² + 26²

a² = 37² - 26²

a = √37² - 26²

a = √(693)

a = 26.324893162m

Approximately = 26.3 m
