Step-by-step explanation:
Given that,
The length of a ladder, H = 20 feet
The height of the wall, h = 15 ft
We know that,
h is perpendicular and H is hypotenuse
So,
Now using Pythagoras theoerm,
Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
Answer:
7 children.
Step-by-step explanation:
Since there were some children already hiding, and adding 5 more children made there be 12 children hiding, we can subtract 12-5 to get 7, or the amount of children initially hiding.

Answer:
2.5 cm
Step-by-step explanation:
The ratio of side lengths of similar figures is the same as the ratio of any linear measure on those figures, including perimeter. The second figure's perimeter is 10/16 of that of the first figure, so the shortest side of the second figure will also be 10/16 of the length of the shortest side of the first figure.
(10/16)×(4 cm) = 2.5 cm
The shortest side of the second polygon has a length of 2.5 cm.
