Question 4
So the polygon has 10 sides, to calculate how much all the interior angles are summed up, you have to see how many triangles you can fit into the polygon (this works for any polygon), in this case it is 8 (see file attached). Therefore you do 8 x 180 = 1440, so the overall angle is 1440º. Now you do 1440 : 10, because there are 10 equal angles, and that is 144º.
Every angle has 144º
question 5
Bearings are always measured clockwise and you always start north. You are at point A and want to go to point B, how much do you have to turn (clockwise!!)?
345º
The picture in the attached figure
we know that
if m ∠DAB=23.5°
then
arc DB=23.5°------> by central angle
the answer isarc DB=23.5°

Answer: The vector represents its new position is (10,25)
Step-by-step explanation:
A bird starts from the ground, that is (0,0) position and flies at a certain speed for 5 seconds, and lands on a tree branch.The vector representing its position is (4,10).
The rate of increase = slope will be
Slope = 10/4 = 2.5
It continues to fly in the same direction and at the same speed for 5 or more seconds
Since it is travelling at same speed and time, Slope will be the same
Slope = (y - 10)/(x - 4) = 5/2
The new x position = 4 × 5/2 = 10
The new y position = 10 × 5/2 = 25
The vector represents its new position is (10 , 25)
Answer:
8.60 miles
Step-by-step explanation:
If S=station G, not shown on the map, is 5 miles east and 7 miles south of Station A, the approximate distance between Station E and Station G when traveling by subway will be gotten using the Pythagoras theorem.
EG² = 5²+7²
EG² = 25+49
EG² = 74
EG = √74
EG = 8.60 miles
<em>Hence the approximate distance between Station E and Station G when traveling by subway is 8.60miles</em>
