Answer:
Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as
where
b is the base
h is the height
Here we have:
Therefore, the area of the triangle is:
Answer:
230°
Step-by-step explanation:
1. A quadrilateral is a 4-sided shape that consists of 2 triangles.
2. The interior angles in a triangle equal 180°: a quadrilateral has interior angles of 360°.
3. x° + 25° + 45° + 60° = 360°
4. x° + 130° = 360°
5. x° = 230°
Answer:
-8
Step-by-step explanation:
well since the equation has the <em>same base</em> of 11, you can just solve for x as you normally would. so the question becomes:
4x+1 = 3x -7
<em>subtract one from both sides</em>
4x = 3x - 8
<em>subtract 3x from both sides</em>
x = - 8
