Answer:

169 m

Step-by-step explanation:

See the image below.

Line AB represents the monument and line BC its shadow

Line DB represents the man and Line BE it shadow.

The Sun’s rays are parallel, so AC||DE.

Then ∆ABC ~ ∆DBE

AB:BC::DB:BE

x/65.8 = 1.8/0.7     Multiply both sides by 65.8

       x = 65.6 × 1.8/0.7  

       x = 65.6 × 2.571

       x = 169 m

The height of the Washington monument is 169 m.

Answer:

x = 9

Step-by-step explanation:

y = 2/3x - 6

If the y point is 0, then plug that number into the equation and solve for x.

0 = 2/3x - 6

Add 6 to both sides of the equation.

6 + 0 = 2/3x - 6 + 6  or  6 = 2/3x

Multiply both sides by 3.

3 x 6 = 2/3x x 3   or 18 = 2x

Divide both sides by 2

18/2 = 2x / 2   or 9 = x
