Answer:
The answer is 48.
Step-by-step explanation:
There are 4 triangles in each square. So multiply 4 by 12 because thats how many squares there are.
Answer:
Area is the total surface covered by the shape and perimeter is the total length of the shape.
11. 8/7
14. 13/10
17. 11/14
81.
Add them all and then divide by the number of days (by 5)
Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)
