Answer:

3

Step-by-step explanation:

Since it's at the same time of the day, the ratio between the height of the person and the shadow they cast will stay the same. So the man's height to shadow ratio is 6:8 = 3:4. The son's height to shadow ratio would be the same so x:4 = 3:4 therefore his height is 3 feet.

If 2xº and (2x - 20) are a pair of adjacent supplementary angles, find the<br>value of x.​
kifflom [539]

Answer:

x = 50

Step-by-step explanation:

Since the two angles are supplementary, add them together and set them equal to 180 degrees

2x + 2x - 20 = 180          Combine like terms

4x - 20 = 180

   + 20   + 20                 Add 20 to both sides

4x = 200                        Divide both sides by 4

x = 50
