Answer:
Question no 2: shape 1 = 4x180=720 / shape 2= 720/6=120
Step-by-step explanation:
Shape 1 :
The reason we multiply 4 by 180 is because the sum of interior angles of a triangle sum up to 180 and there are 4 triangles so you multiply 4x180 to get 720.
Shape 2 :
In a hexagon all the sides are of the same length (congruent) and all the interior angles are all the same size (congruent) So the find the measure of the interior angles we know that the sum is 720 and there are six angles so... we divide 720/6 which gives us 120
Answer:
29.5 feet
Step-by-step explanation:
A firefighter extends a ladder against the side of a house. The ladder makes a 32°\degree° angle with the ground. The base of the ladder is 25 feet from the house. Find how high the ladder reaches up the side of the house to the nearest tenth of a foot.
We solve using Trigonometric function of Cosine
= cos theta = Adjacent/Hypotenuse
Theta = 32°
Adjacent = 25 feet
Hypotenuse = Height of the ladder
= cos 32 = 25/x
x = 25/cos 32
x = 29.479460084 feet
Approximately= 29.5 feet
