6x + 5y = 7 and 2x + 3y = 3
ra1l [238]
6x + 5y = 7
-6x - 9y = -9

-4y = -2

y = 1/2 or 0.5

2x + 3(1/2) = 3
2x + 1.5 = 3
2x = 1.5

x = 0.75

A surveyor is standing at a distance of 50 feet from the base of a building. From this point, the angle of elevation to the top
zalisa [80]

Answer:

The height of the building is approximately 29 feet

Step-by-step explanation:

We are given

A surveyor is standing at a distance of 50 feet from the base of a building

so, b=50 feet

Let's assume height of the building is h feet

angle of elevation is 30°

\theta=30

we can use trig to find h

tan(\theta)=\frac{h}{b}

now, we can plug values

tan(30)=\frac{h}{50}

h=50\times tan(30)

h=28.8675
