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:
4:5
Step-by-step explanation:
Since there are nine marbles in the bag, and 4 are red and 5 are blue, then you know that the ratio to red and blue is 4:5
Answer:
x=-7
Step-by-step explanation:
8x - 2 = -11 + 7x + 2
First, separate the terms: move x to one side
subtract 7x from both sides
8x -7x - 2 = -11 + 7x -7x + 2
x - 2 = -11 + 2
Now get x by itself by adding 2 to both sides
x - 2 +2 = -11 + 2 +2
x = -11 + 4
simplify
x = -7
you're welcome
It would be simplified to 1/21
