Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet

Step-by-step explanation:

The scenario is shown in the attached photo.

Right angle triangle ABC is formed when the ladder leans against the wall of the house.

AC = the height of the ladder

AB = x feet = distance of the base of the house to the foot of the ladder

BC is the wall of the building.

To determine x, we will apply trigonometric ratio

Cos # = adjacent/hypotenuse

Where

# = 70 degrees

Hypotenuse = 20

Adjacent = x

Cos 70 = x/20

x = 20cos70

x = 20 × 0.3420

x = 6.84 feets

baherus [9]

Answer: 30%

Step-by-step explanation:

Percent error = \dfrac{|\text{Estimated value - Actual value}|}{\text{Actual value}}\times100\%

Estimated number of games win this year = 7

Actual number of games won = 10

Now ,   the percent error of Doug’s estimate = \dfrac{|7-10|}{10}\times100\%= \dfrac{3}{1}\times10\%=30\%

Hence, the percent error of Doug’s estimate = 30%
